It is stated that the Hammers wanted to add the former Arsenal man as their fourth striker, but the 26-year-old has turned down the chance to move back to London, so he can stay with Real Sociedad.
The Mexican international, who has scored 57 goals in 158 games for Sociedad, has a release clause of £21 million, according to the report, and the club are willing to pay that amount. However, it appears as if Vela himself is not looking for a move, and will reject any further advances if the Hammers retain their interest in him.
Is Vela needed at West Ham?
The report states that West Ham are looking to add Vela as a fourth forward in their ranks. Andy Carroll, Diafra Sakho and Enner Valencia are ready to be called upon, but injuries to the former pair last term removed much of their attacking threat.
Vela would provide cover should their injuries return, whilst his ability to play on the wing also means he offers a different type of threat to the more poaching style of Carroll and Sakho.
However, for £21 million, you would be expected to sign a top class forward, and not a glorified back-up option, and the Hammers should be looking to spend their money on a different target this summer.
