West Ham have bid €30 million for a "top forward" in Ligue 1 and are preparing another major move for a player in England, co-owner David Sullivan says.
Sullivan did not mention the players by name, but multiple reports in English newspapers on Monday night reported West Ham are interested in a pair of Belgium internationals: Marseille's Michy Batshuayi and Liverpool's Christian Benteke.
The Hammers have also previously been linked to Lyon star Alexandre Lacazette and Arsenal's Theo Walcott.
Speaking to Sky Sports on Monday, Sullivan said the club are looking to spend big ahead of their move to the Olympic Stadium.
"We are hopefully going to bring one or two top players in," he said. "We put in a bid today for €30m (£23.7m) for a top forward in France and other bids will be going in.
"We are going to make a £20m or £25m bid for a player in England this week. So whatever happens, we'll bring a top striker in.
"It's a statement of intent. We'll spend between £30m-£50m on transfers this summer.
"But you've got to build it up gradually. You can't compete with the likes of Manchester United overnight. The Olympic Stadium gives us about £12m extra revenue a year, but not £100m.
"We might have to put our own money in -- we've done it before -- but we hope we're clever enough for the €30m bid."
