West Ham have made a bid worth €40m (£33.75m) for Lyon midfielder Lucas Paqueta.
The player’s agents are in London and want to conclude a deal with a Premier League club before the end of the window. Talks are continuing between the clubs.
Paqueta, who played in the Europa League last season against West Ham, has three years left on his Lyon contract.
Meanwhile, talks are continuing with Club Brugge over the signing of Belgium midfielder Hans Vanaken.
A gap in valuation still exists. Vanaken, who turns 30 on Wednesday, wants to come but West Ham are prepared to walk away from the deal if the asking price doesn’t come down.
West Ham are also looking at other options including Atalanta’s Ruslan Malinovskyi. The Hammers are keeping an eye on Conor Gallagher’s situation at Chelsea. If he is allowed to leave, West Ham are very interested in doing a deal.
David Moyes is determined to strengthen his squad after speaking of his frustrations in the transfer market, with his side currently bottom of the Premier League after three defeats in their opening three games.
It is their worst start to a season for 51 years and they are also the only team in all four divisions yet to score a goal.
