Hardest squads in the Premier League – who are the toughest? From least to most fearsome, we’ve ranked them all!

There must have been a little something extra in Premier League water bottles at the weekend.

Fights broke out in two games as Manchester City and Chelsea players locked horns at Stamford Bridge before West Brom and Watford stars scrapped at the Hawthorns.

Sergio Aguero, Fernandinho and Roberto Pererya all saw red, while other players fought their way into the referee’s little black book.

The era of the Premier League hard man ended as the likes of Roy Keane, Duncan Ferguson and Vinnie Jones all drifted out of the game.

But, when push comes to shove, which current teams couldn’t fight their way out of a paper bag, and which squads shouldn’t be messed with?

Click the right arrow above to see our light-hearted look at the hardest Premier League squads…

20 20. Swansea City – When you see the Premier League table and the players the Jacks have at their disposal, a lack of fearsome stars might just be a contributing factor. We cant say Kyle Naughton or Leroy Fer would pose much of a threat if a scrap did take place, Fernando Llorente, despite his imposing frame, would presumably duck, dodge and dive away from any fisticuffs in fear of damaging his handsome face.

20 19. Hull City – Wed love to chronicle their misdemeanours but there arent many and they seem a nice bunch. After just 19 yellow cards all campaign, wed describe them as harmless but, as theyve had two red cards this season, well upgrade that to mostly harmless.

20 18. Southampton – Saints by name, Saints by nature, we reckon. They might have the imposing figures of Virgil van Dijk, Fraser Forster, Jose Fonte and Oriol Romeu but we imagine if the going got tough the rest would hide behind them rather meekly. Theyre young scallies rather than thuggish brutes.

20 17. Bournemouth – The Cherries seem like a good-natured bunch, hardly capable of getting into any trouble. In fact, with Harry Arter, Jack Wilshere, and Adam Smith, they seem more likely to tell tales, even though they started it.

20 16. Arsenal – More of an irritating group of midges and mites, than a set of players you need to be afraid of. Lots of pushing, shoving, pinching and pulling, but they would never throw a punch.

20 15. West Ham United – They might have Slaven Bilic in charge and once had the likes of Tomas Repka in their ranks but this group of Hammers lack any kind of grit and iron right now. They look like they would be all mouth and no trouser, with a scattergun approach to a battle. We expect any fight would involve plenty of posturing with clenched fists before some misdirected windmilling.

20 14. Sunderland – The Black Cats are the kind of team who want to avoid a scrap at all costs. They have a couple of big guys, including Victor Anichebe, Papy Djilobodji and Jan Kirchhoff, who could inflict some damage but are better represented by Didier Ndong and Duncan Watmore, who would run around in an attempt to tire and bamboozle opponents before a sucker punch. Lee Cattermole's best days are behind him too.

20 13. Middlesbrough – Boro, as a squad, seem more likely to break up a fight than start one. Midfield destroyer Marten de Roon and Alvaro The Beast Negredo could be ones to watch out for if anything does get ugly.

20 12. Manchester City – If were honest were a little surprised City lost their cool against Chelsea. Aleksandar Kolarov does have the cold stare of a trained assassin, but as for the rest of the team, they all seem like they would be disinterested if any kind of serious trouble arose. Kevin De Bruyne could be a little spiteful, though.

20 11. West Bromwich Albion – Outmoded stereotypes have the Baggies as scrappers and fond of the dark arts. In reality, theyre hardly very menacing and only James McClean and Claudio Yacob are going to cause trouble, while Darren Fletcher mouths off. Dont expect the likes of Nacer Chadli and Matt Phillips to get stuck in; they are the friendly faces of West Brom now.

20 10. Watford – While no one Hornets player would stand out as a magnet for trouble, their players keep getting themselves into it. Miguel Britos, Roberto Pererya, and Ben Watson have seen red this season, but they hardly seem like the types to cause trouble. Valon Behrami is someone who wont shy away from any fights, along with Troy Deeney.

20 9. Liverpool – A wily and mixed group of battlers form this squad. Jordan Henderson is the yappy, terrier-like, leader, very capable of dragging his mates into a scrap, while everyone else is telling him to leave it. We expect Adam Lallana, Emre Can and Dejan Lovren are capable of some dirty tricks, while Roberto Firmino might be the surprise of the bunch  dark horses.

20 8. Stoke City – Similar to West Brom, this leopard has begun to change its spots. A once fearsome and brutish unit, the Potters now have Joe Allen as their most ill-disciplined star. Ryan Shawcross, Marko Arnautovic and Charlie Adam wouldnt shy away from a scrap though, so keep on your toes. Phil Bardsley, meanwhile, has a good punch, as Wayne Rooney can attest to.

20 7. Everton – The Peoples Club  but theyve definitely got a nasty streak. Seamus Coleman seems capable of getting himself into trouble, while Gareth Barry and Idrissa Gueye are unlikely to back down from a battle. Ross Barkley is going to stick up for his team-mates, but dont expect Romelu Lukaku to get involved, we doubt he can be bothered to get involved.

20 6. Chelsea – Without doubt, Diego Costa is the biggest b*****d in the Premier League. Capable of starting a fight in an empty room, he sprinted fast than he had all game when he leapt off the bench to get involved in the scrap at the Etihad on Saturday. David Luiz, Pedro, Cesc Fabregas, and Eden Hazard are also likely protagonists in any ugliness, but unlikely to be able to back it up when push comes to shove. Antonio Conte's pretty hard, mind.

20 5. Burnley – Sean Dyche is the Don. You dont mess with a man who has a passing resemblance to Stone Cold Steve Austin. Hes the leader of some renegades ready to mix it up. Sam Vokes is the muscle, Steven Defour the scrapper and George Boyd the man tasked with tiring out the opposition and leading them into a trap. Teamwork is the key to their success.

20 4. Crystal Palace – Alan Pardews men are more dastardly than outright brawlers, the Eagles have a group of players you dont want to mess with. Watch out for Damien Delaney and Scott Dann, they take no prisoners. Tough as old boots and willing to get stuck in, by foul or fair means, they have trouble finishing off opponents though.

20 3. Manchester United – The Red Devils squad seem like theyre spoiling for a fight. The sneaky Ander Herrera, and the henchman-like Marcos Rojo arent going to stand for any disrespect, while Zlatan Ibrahimovic has martial arts training behind him. Dont mess with them or Wayne Rooney will put you to sleep  and watch out for Marouane Fellainis sharp elbows.

20 2. Leicester City – Would you mess with Wes Morgan and Robert Huth? Were surprised Premier League strikers go anywhere near them. Jamie Vardy and Danny Drinkwater also have a bit of the devil about them. The only problem is, their 'Winston Wolfe', NGolo Kante, can no longer get them out of trouble.
