Slaven Bilic has got his man the second time around in Manuel Lanzini.
The Hammers boss was keen to take him to Besiktas two years ago but said: “Then it it was very difficult. We were close but now the chance came that we could get him and of course he’s going to help us a lot.
He’s going to add even more creativity in the crucial parts of the pitch.
The boss told West Ham TV: “He’s a good player and we are happy that he joined us.
At just 20 years of age they gave him the No10 shirt at River Plate, which is a massive club, of course.
“I am confident and I’m hopeful that he can adapt. We’re going to see. He’s not very strong but he rides challenges, he doesn’t go down.
“So I hope he could be bingo for us. I am really hopeful and I think I have a feeling that he’s going to help us a lot.”
