Henry Onyekuru to West Ham United

West Ham have joined the race to sign KAS Eupen's 19-year-old striker Onyekuru, according to the Mirror.

Onyekuru has scored eight league goals in eight appearances for the Belgian side this season, and his performances have attracted the attention of a number of clubs around Europe's top leagues, with the likes of Chelsea, Arsenal, Borussia Dortmund and Sevilla all scouting the player. Scottish champions Celtic had a €1 million bid for the Nigerian rejected in January, with the Jupiler League club valuing the youngster at €6m.

Ryan Bennett to Brighton

Norwich City defender Bennett has emerged as a summer target for Brighton, with the south coast club looking to bolster their squad in order to compete in the Premier League next season, according to local outlet the Norfolk Eastern Daily Press.

The 27-year-old signed for the Canaries in January 2012 and has made more than 100 league appearances for the club, including 33 in the previous campaign. Middlesbrough, Swansea City and Hull City have all been linked with the centre-back in the past.

Andre Gray to Everton

Gray's nine league goals have been integral to Burnley retaining their Premier League status this season, with the Telegraph reporting the Clarets might struggle to keep hold of the striker amid interest from Everton. The 25-year-old has just one year left on his current deal, and Burnley might be willing to sell this summer rather than lose him for nothing in 12 months' time.

The former Brentford frontman has also been linked with Tottenham, but the Toffees could have the edge over the north London club if they're able to offer more first-team opportunities.

Michael Keane to Liverpool

Burnley's 24-year-old centre-back Keane has been linked with a number of top Premier League clubs in recent weeks, with Liverpool thought to be close to securing a deal for the former Manchester United man, according to the Mirror. Keane had played every minute of Burnley's campaign until the past two games, with his impressive displays attracting interest from Tottenham and Everton, as well as former club United.

Jurgen Klopp is desperate to bolster his defensive options this summer following some high-profile errors at the back, and he has made the England international one of his top targets.

Sebastien Corchia to Arsenal

Arsene Wenger will turn to Lille defender Corchia to help improve Arsenal's backline, Goal is reporting. The 26-year-old right-back, entering the final year of his contract with the Ligue 1 club, is expected to leave Les Dogues this summer and didn't rule out a move to the Premier League when quizzed about his future. "I have heard about interest from English clubs, but to be honest I don't know what will happen," Corchia told Goal.

Arsenal's first choice right-back Hector Bellerin is a reported target for Barcelona this summer.
