From zeroes to heroes: the Premier League's 20 most improved players in 2016/17

The stars from each club who’ve taken things to a whole new level this season, as selected by Tom Seymour. And yes, he even found one for Sunderland

Arsenal: Theo Walcott

Walcott now has 19 goals in all competitions and is set for his most prolific Arsenal season, with the 21 he scored in 2012/13 within his sights

A baby face and the occasional childish sulk often disguise the fact that Walcott is now the Gunners' longest-serving player, having clocked up 11 years at the Emirates. Now 28, the winger was put out after being excluded from Gareth Southgate's latest England squad, pointing out: “I'm one of the leading goalscorers in the league”.

They may not be quite true, but 10 goals and two assists in 23 appearances this season – and a better minute-per-goal ratio than Jermain Defoe and Jamie Vardy – suggests he may have a point. Walcott now has 19 in all competitions and is set for his most prolific Arsenal season, with the 21 he scored in 2012/13 within his sights.

Bournemouth: Josh King

When the Cherries were promoted to the top flight in 2015, they brought King up from the Championship with them, signing the Norwegian from Blackburn Rovers. The 25-year-old was solid enough last term but has suddenly found his scoring touch in 2016/17: he leads the charts for Bournemouth with 12 league strikes, despite rarely playing as an out-and-out striker.

Burnley: Michael Keane

Keane has been a mainstay for the Clarets since arriving in 2015, having already made over 100 club appearances

Keane has been a mainstay for the Clarets since joining from Manchester United in January 2015, having already made over 100 appearances for the club.

The centre-back has kicked on a few levels after helping Sean Dyche's side to promotion last year, playing a key role in the eight clean sheets they've recorded this season. He's also earned his first two England caps in the process, becoming the first Burnley player to start a match for the Three Lions since 1974.

Chelsea: Victor Moses

Since switching to the wing-back system in September, the 26-year-old has started all but two of the Blues' matches

Many thought Antonio Conte would immediately introduce a three-at-the-back formation upon taking charge at Stamford Bridge, but the problem area seemed to be at right wing-back.

Step forward Moses, who could have been forgiven for thinking his Chelsea career was over after spending the previous three years out on loan. Since switching to the wing-back system in September, the 26-year-old has started all but two of the Blues' matches - and both of those absences were injury-enforced.

Crystal Palace: Wilfried Zaha

After promising so much as a teenager, a high-profile move to Manchester United in January 2013 halted Zaha's progress. Now back at the club which provided him the platform to earn that transfer to Old Trafford, the 24-year-old finally looks to be realising his vast potential with six goals and seven assists in the league this term. In his previous 79 top-flight appearances, he'd managed only six goals and four assists.
