West Brom have completed the signing of Nacer Chadli from Tottenham for a club record fee of £13m on a four year deal.
Baggies boss Tony Pulis said: "He's a top, top player and I'm delighted we've got him.
"I said last week that these signings all had to be about players who would improve our squad - and Nacer does precisely that."
Chadli said: "I feel very good to be here. It came very quickly but I spoke to the club and they have a good team, a good manager and I am very pleased to be here.
"My ambitions? I just want to help the team win as many games as possible."
