The January transfer window is officially over, and even though this year’s edition might go down as one of the most boring and disappointing in recent history, multiple teams made impressive signings.

Here are the grades for all 20 English Premier League team.

Arsenal (B+): Is Arsene Wenger’s days of being the laughing stock of the transfer window over? The Frenchman only signed two players, but they could prove enough for his side to finally press Chelsea and Manchester City for the title next season – this season has already being decided with either the Blues or the Citizens winning the coveted title.

Krystian Bielik, 17, and Gabriel Paulista, 24, are not the most enticing players in the world, but they offer depth in their respective positions. Unlike Paulista, Bielik won’t feature much this season, but if Wenger is right, the Polish youngster could be the next top defensive midfielder.

Aston Villa (B): Rapidly diving down the premier league table, Paul Lambert has brought in two offensive talents to help save his team and his job. Former breakout star Scott Sinclair has been rescued from Manchester City’s bench and one could only imagine that he desperately wants to impress his new employer. Carles Gil has left Spanish football for English football and the attacking midfielder could be the player to help Christian Benteke regain his mojo.

Burnley (D): For a side that’s currently one place above the relegation zone, Burnley was too quiet in January. The club permanently signed ex-Manchester United defender Michael Keane, but that won’t save their season.

Chelsea (A): Jose Mourinho’s side has to be awarded 100 just for participation. The rich and already complete club flaunted its money in everyone’s face and signed one of the star performers of the 2014 World Cup, Juan Cuadrado. The Colombian adds more to Mourinho’s vicious attack.

Crystal Palace (B+): You can tell Alan Pardew is enjoying his new job, because the manager went out and signed a bunch of difference makers. He acquired Arsenal’s Yaya Sanogo on loan, bought Jordan Mutch, Wilfried Zaha, Lee Chung-Yong, Keshi Anderson and adding insult to Newcastle United’s pain by signing the Magpies fan favorite Shola Ameobi.

Everton (C): For a manager that might lose his job after his side’s horrific start, Roberto Martinez was relatively calm during the window. The Spanish manager only brought in speedster Aaron Lennon on loan and let Samuel Eto’o leave. Lennon is good, but the winger won’t solve Everton’s issues.

Hull City (B-): Steve Bruce’s side has only scored 20 goals this season and is currently in one of the three relegation spots. Because of his side’s tentative situation, the manager acquired Senegalese striker Dame N’Doye. The experienced finisher has a good track record and should help the Tigers move up the table.

Leicester City (A-): It has to be said, Nigel Pearson did some good work in January. The manager convinced extremely talented Croatian forward Andrej Kramaric to forgo bigger clubs and join the bottom feeders and he signed two premier league veterans, Robert Huth and Mark Schwarzer.

Liverpool (F): Stuck in seventh place and desperately seeking to get back to the UEFA Champions League, Brendan Rodgers decided not to strengthen his side. Even with Daniel Sturridge’s return, the current Liverpool side can’t overtake Arsenal, Tottenham Hotspur and Southampton.

Manchester City (B): Wilfried Bony could be the best singing of the transfer window. The lethal forward adds to City’s impressive arsenal and his chemistry with Yaya Toure should make it easy for him to adapt to the new system.

Manchester United (D): Louis van Gaal only added two squad players to his side in January. The Dutchman signed former Barcelona shot-stopper Victor Valdes and youn defender Andy Kellett.

Newcastle United (F): The change of manager makes the clubs inactivity in January understandable. However, the club could use one or two fresh legs.

Queens Park Rangers (D): The London club gave Mauro Zarate a way out of West Ham, but the Argentine won’t turn the team’s season around. And now that Harry Redknapp has resigned, QPR’s days in the premier league look limited.

Southampton (B): Ronald Koeman improved his team’s chances of making the champions league by signing two players he is very familiar with, Eljero Elia and Filip Djuricic. Elia has already impressed since he arrived from Werder Bremen and if given the opportunity, Djuricic should be a solid addition.

The club also sign fullback Ryan Bertrand permanently.

Stoke City (B-): With some players returning from injury and a respectable 10th place position, Stoke didn’t have to make any acquisitions, but the club steal signed German center back Philipp Wollscheid. The team lost standout performer Bojan Krkic, but Mark Hughes will find a way to make up for the loss.

Sunderland (C): Getting Jozy Altidore off their payroll was a big win for Sunderland. The American forward returned to MLS and Jermain Defoe headed the other way. Defoe might be in the final days of his career, but that doesn’t stop him from scoring goals.

Swanseas City (B-): The club lost its top scorer, but gained multiple contributors. Jack Cork is an experienced midfielder that can fill multiple positions, Kyle Naughton is desperate for a fresh start, Matt Grimes is a talented youngster that could grow into a big time player and Nelson Oliveira will certainly cherish the opportunity to prove himself in the premier league.

Tottenham Hotspur (C): The club already has a good group of player that could compete for a top four finish, which is why Mauricio Pochettino elected to only sign 18-year-old Dele Alli and loan him back to MK Dons.

West Brom (B-): Callum McManaman and Darren Fletcher are fantastic signings and they should be able to keep the club in the premier league.

West Ham United (D): Since starting the season in fine form, West Ham has slowly regressed and Sam Allardyce failed to strengthen his squad. The manager only signed young Canadian center back Doneil Henry.
