West Ham United boss Sam Allardyce doesn't expect an instant impact from Wellington Paulista.

The Brazilian striker signed for the Hammers last week.

Allardyce told whufc.com: "I think he's a talented player in terms of his ability on the front line. Let's see if we can apply the talent into the team as quickly as possible. I don't know how quickly that's going to be, sooner rather than later hopefully, but it might take a little while. Talent is the most important thing and then applying that talent where it's most difficult in the Premier League and that's in the final third."
