The first signing of Jose Mourinho's second spell at Chelsea is the Germany forward Andre Schurrle from Bayer Leverkusen.
Bayer Leverkusen's Andre Schurrle signing on for Chelsea
Schurrle, 21, has long been a target for Chelsea and the club confirmed a deal on Thursday, thought to be worth £18 million (Dh103.5m).
It had been expected that Chelsea midfielder Kevin de Bruyne would move on loan as part of the deal, following a successful spell in the Bundesliga at Werder Bremen last season.
However, Chelsea's statement made no mention of the Belgian midfielder, with Mourinho suggesting at Monday's news conference that the player was very much in his first-team plans for the future.
Mourinho, who agreed a four-year deal to return to Stamford Bridge following his departure from Real Madrid, admitted it was "normal" to expect some fresh faces to be added to the squad.
However, the new Chelsea manager, who won the Champions League for a second time with Inter Milan after leaving Stamford Bridge six years ago, maintained he was also looking to bring on the club's younger players in the new campaign.
"These kids - and I say that respectfully - have big potential and big space for improvement. They've not reached their best level," he said. "The stability the owner and I can give them is related to work - in the methods, the coaching philosophy, in my leadership, in everything that can help them improve.
"When you mix with them those who are over 30, we will keep a balance and try to go on."
