West Ham are in talks to sign £22million-rated Porto striker Moussa Marega, according to reports.
The deal, which could fall in price if Hammers midfielder Cheikhou Kouyate heads the other way, would take the club’s summer spending past £100m.
Malian forward Marega, 27, struck 23 times as Porto won the Primeira Liga title last season, their first championship in five years.
Talks have taken place between the two teams’ representatives over a £22m switch, according to reports.
But Porto could cut their asking price if Kouyate is included in any deal.
West Ham’s transfer expenditure this summer currently sits at £94m, with new boss Manuel Pellegrini having already brought seven new faces with him to the London Stadium.
A club-record £41m deal for Lazio’s Felipe Anderson added to the £22m spent on Issa Diop and £17.5m paid to Borussia Dortmund for Andriy Yarmolenko.
Lukasz Fabianski joined for £7m from Swansea City while West Ham also paid £3.5m for Fabian Balbuena.
Free agent signings Jack Wilshere and Ryan Fredericks, moving across London from Arsenal and Fulham respectively, were the only arrivals not to dent the club’s transfer budget.
The Hammers’ spree ranks second in the Premier League this summer, with only Liverpool’s £175m outlay surpassing them.
Pellegrini has shown no signs of ending his transformation of the squad, saying: “We are trying to build a strong squad.
“We all know that the Premier League is not easy so we don’t just need to have a good team, we need to have a good squad.
“For the moment we have seven new players and we also have three important players injured that we don’t know when they can return – (Manuel) Lanzini, (Andy) Carroll and (Declan) Rice.
“Until the last day that we have time to bring players (in), we will try to build a strong squad.”
Senegal captain Kouyate, 28, has been linked with a move away all summer, with Crystal Palace and Wolves reportedly interested.
The defensive midfielder has been a mainstay in the Hammers side since joining from Anderlecht in 2014, racking up 147 appearances in four years and scoring 15 times.
He played in all three of Senegal’s World Cup games as they were cruelly knocked out at the first hurdle.
The Lions of Teranga sat equal with Group H rivals Japan on four points but exited the tournament under the fair play rules, by virtue of picking up more yellow cards.
