West Ham are on the brink of completing a £36.5m deal for Brazilian midfielder Lucas Paqueta.
The deal for Paqueta also includes a potential £14.4m in add-ons which, if triggered, would turn the transfer into a club record for the Hammers.
Paqueta, who will sign a five-year deal, joined Lyon for 20m euros (£17m) from AC Milan in 2020.
He is expected to be part of the Brazil squad for this year's World Cup.
Paqueta scored nine goals and contributed six assists in 35 Ligue 1 appearances last season.
He has scored seven times in 33 games for Brazil and played for Lyon against West Ham in last season's Europa League quarter-final, which the Hammers won 4-1 on aggregate.
