West Ham look likely to bring their summer signings to at least six by the end of the week.

The Hammers have confirmed the signing of Jack Wilshere. The former Arsenal midfielder, who has had injury issues throughout his career, underwent a comprehensive medical over the weekend and signed a three-year deal on Monday.

West Ham are also poised to sign Ukraine winger Andriy Yarmolenko from Borussia Dortmund for £17.5million. The 28-year-old only joined from Dynamo Kiev last summer but struggled to find his top form in the Bundesliga. The third potential arrival is Paraguay central defender Fabian Balbuena. West Ham have agreed a fee of around £3m for the 26-year-old, who plays in Brazil for Corinthians.

Meanwhile, reports in Italy suggest that West Ham are closing in on a club record £38m deal to sign Lazio’s Brazil winger Felipe Anderson.
