Stamford Bridge side welcome in Anzhi midfielder.
Chelsea have confirmed the signing of Brazilian attacking midfielder Willian from Anzhi Makhachkala on a five year contract after he was granted a work permit according to the club’s official website.
The Blues are understood to have paid in the region of £30million for the 25-year-old who had a medical at Stamford Bridge last weekend.
On completing his move, Willian said: ‘I’m very happy to be here, it’s been a dream of mine to come and play here.
‘Chelsea are one of the best clubs in the world, and now I’m going to play for one of the best managers in the world, so I’m very happy and looking forward to it.’
Tottenham were close to landing the former Shakhtar Donetsk man after passing a medical last Wednesday but Chelsea owner Roman Abramovich intervened and offered him an improved deal to sign for the Stamford Bridge club instead.
The Brazilian international, who came through the Corinthians youth academy, had made the switch to the Russian Premier League from Shakhtar in a reported £30m move last summer but he was made available for transfer after the club’s owner Suleyman Kerimov withdrew funds.
Willian will become the third signing of the transfer window following the acquisitions of German international Andre Schurrle and Dutch midfielder Marco van Ginkel.
He will not feature for Mourinho’s side during Friday’s UEFA Super Cup match against Bayern Munich in Prague and will therefore not have a chance to make his debut until after the international break when the Blues face Everton on September 14.
