Mauro Zarate has completed a permanent transfer to Fiorentina, West Ham announced on Thursday night.

The striker underwent a medical with the Italian club earlier in the day, and has now wrapped up a move back to the Serie A in a deal believed to be worth L1.5million.

Although West Ham did not specify the length of Zarate's new contract with Fiorentina, sources in Italy believe the Argentine forward has put pen to paper on a two-and-a-half-year deal.
