West Ham United are preparing to join the race for Nice midfielder Jean-Michael Seri.

Seri has been a long-term target for Arsenal, while Chelsea have reportedly entered in advanced talks over a potential deal.

West Ham are now ready to ruin Blues' plans with a late £35m offer that would activate the player's release clause.

Seri is determined to leave France and would prefer a move to the Premier League, although Napoli and Borussia Dortmund are also interested in his services.
