West Ham lead the chase to sign Yannick Bolasie from London rivals in the wake of Andros Townsend’s switch to Selhurst Park, according to a report.

The Sunday People claim the Hammers are one of a number of Premier League clubs approaches about the 27-year-old winger.

It is said that Palace have set a £20million-plus price tag on Bolasie following his eyecatching performances in the past two seasons.

A string of top clubs, including Spurs, Everton, Manchester United and Liverpool have all asked to be kept informed of events, although it is reportedly too early to say they will make bids for the DR Congo international.

West Ham are keen to land Bolasie and have been encouraged by the fact that he is settled in the capital and would prefer to stay put rather than moving north.

Slaven Bilic has already signed one winger this summer in the form of Algeria international Sofiane Feghouli on a free transfer and is hopeful of adding another.

Bolasie joined Palace from Bristol City in the summer of 2012 and has made 143 appearances for the Premier League club, scoring 13 goals and supplying 30 assists in his spell at the club.

In other West Ham news, the club have adjusted their striker targets and have centred their attention on a free-scoring Premier League man.
