West Ham are closing in on the signings of Niclas Fullkrug and Guido Rodriguez as they look to continue their summer spending.
Both Fullkrug, who plays for Borussia Dortmund, and Rodriguez, who is currently a free agent, flew in on Saturday to undertake their medicals with the Hammers.
Meanwhile, winger Crysencio Summerville arrived from Leeds United on Saturday and signed a five year contract with Julen Lopetegui's side.
Talks have been ongoing over a deal for the attacking talent who has two years remaining on his existing contract at Elland Road after joining in a bargain £1.3m transfer four years ago.
It was previously suggested that the Hammers were looking at pulling out of talks as they believed the price, believed to be in the region of £35m - £40m, was too expensive.

However, the two clubs have now got a deal over the line.
Summerville has been keen to return to the Premier League as Leeds missed out on promotion after being beaten by Southampton in last season's play-off final.
The 22-year-old has agreed personal terms and signed a five-year contract with West Ham as they attempt to commit the player to a long-term stint in London.
The Hammers are currently away on pre-season duty in the United States, with Summerville set to fly out to join his new team-mates.
Meanwhile, West Ham remain interested in Man United full-back Aaron Wan-Bissaka, however the Red Devils are holding out for £18million for the defender.
Should they sell, they would then look to hold further negotiations with Bayern Munich for right-back Noussair Mazraoui.
United had a bid for Mazraoui and teammate Matthijs de Ligt rejected last week.
