West Ham will have to pay up to £25m to sign Chelsea striker Tammy Abraham, according to reports in the UK.

Multiple sources have suggested that the England international is a top target for the Hammers in the summer transfer window but his asking price could prove problematic.

Despite not being in manager Thomas Tuchel’s first-team plans, the Blues are not willing to sell Abraham at a discount. The 23-year-old remains the club’s top scorer this season with 12 goals and they will expect clubs to match their demands for the player.

With that being the case, it is likely that West Ham would have to pay the transfer fee in instalments, with finances still tight due to the impact of the global health crisis.

The Irons did reportedly offer £27m for Sevilla striker Youssef En-Nesyri during the January transfer window but, since then, the London club have signed Said Benrahma on a permanent basis from Brentford for an initial £25m.
