With 20 games gone in the Premier League, Paul Merson picks out his stars of the season so far.

Chelsea remain top of the table despite Wednesday's 2-0 loss at Tottenham and Merse has plenty of praise for some key contributors to their 13-match winning streak.

The Magic Man has also picked out a 22-year-old he reckons is in contention for an England call-up and his favourite of two stellar scorpion kicks...

Best summer signing: N'Golo Kante (Chelsea)

He won the league with Leicester and if you look at how they are doing now and how Chelsea are going, he has to be the signing of the season so far. He gives them legs in midfield and has been crucial in transforming their fortunes.

Best youngster: Nathan Redmond (Southampton)

He's another great signing. He's done great at Southampton and when he's not in the team they're a different side, which we saw when he was suspended. I'd say he's not far off an England call-up.

Most people will be saying Dele Alli but he has just done it the last four games and I thought he'd been poor at the start of the season. He's back to the top of his game now but his recent form covers a disappointing start.

Top manager: Antonio Conte (Chelsea)

I know it's a bit obvious given where they were and where they are now but it has to be Conte. Even though it came to an end on Wednesday, it's incredibly difficult to put together that run in this league - even more so considering it's his first season in England.

The other one I'd mention is Tony Pulis, who is doing a phenomenal job when you look at the sides West Brom are above. The fact they're talking about getting Morgan Schneiderlin shows how far they've come.

Best goal: Olivier Giroud (Arsenal, v Crystal Palace)

Well that's obvious as it only happened last week - Giroud's scorpion kick. I don't want to be a party-pooper with Henrikh Mkhitaryan one but he was offside.

If he'd been onside, he wouldn't have had to do that. There have been a lot of other great goals but you judge a goal on your reaction and when Giroud scored mine was just: wow.

Best performance: Bournemouth (4-3 v Liverpool)

Bournemouth were playing against a side who were flying and they were getting run ragged and rinsed in the first half. A lot of other sides would have capitulated at 3-1 down and to come back and win 4-3 against a really good Liverpool team was fantastic.

Unsung hero: Victor Moses (Chelsea)

The shift he puts in! You talk about Eden Hazard and Diego Costa but Moses has been as important as anyone in making this system work for Conte and he's also scored some important goals. To consider he'd never really played that role before is just incredible.

Player of the season: Diego Costa (Chelsea)

I'm going to go for Costa. He's been outstanding. I think he's the one who has been dragging Chelsea along when they were winning but weren't playing that well. He's scoring important goals and is head and shoulders above what he was last year.
