Chelsea have formally announced the signing of Andre Schürrle from Bayer Leverkusen today.
The Blues confirmed earlier this month that they had come to an agreement with Leverkusen over a deal for the 22-year-old German international, subject to personal terms being agreed and a medical.
Now Chelsea have announced the completion of the deal, confirming that Schürrle has signed a five-year contract and will wear the number 14 shirt next season.
A statement on chelseafc.com read: "Chelsea Football Club is delighted to announce the transfer of Andre Schurrle from Bayer Leverkusen.
"The 22-year-old moves to Stamford Bridge from the Bundesliga club, whom he joined back in 2011.
"It was announced on 13 June that Chelsea FC and Bayer Leverkusen had reached an agreement for Schurrle's transfer. He has signed a five-year contract and will wear the No.14 shirt.
Chelsea's move for Schürrle looked to have hit a snag earlier this month, with reports suggesting that Leverkusen wanted Blues youngster Kevin de Bruyne as part of the deal - something the Belgian wasn't keen on.
However an agreement was eventually reached between the two clubs, with Chelsea reportedly paying around £20 million for his services.
"I am so happy now I have signed and it is an honour for me to play for this club, with this team and for these great fans,' Schurrle said. "I am really looking forward to it."
The former Mainz midfielder joined Leverkusen in 2011, going on to make 64 league starts for the Werkself. He has 24 caps for Germany, with seven international goals to his name.
