West Ham expect to complete the signing of Simone Zaza from Juventus later on Friday.
Hammers manager Slaven Bilic has confirmed the 25-year-old Italy striker has agreed personal terms over a switch to east London.
"With the Zaza situation, it looks very likely to happen and should happen today," Bilic said at his pre-match press conference ahead of Sunday's trip to Manchester City.
"As far as I know the deal is agreed between clubs. The personal terms are also agreed and he is due in London today, so we hope it will be done.
"It's very positive and it's a boost. We've been trying for a long time now to get a top-quality striker and he was always mentioned."
