Former Bolton Wanderers left-back Marcos Alonso has joined Chelsea for a reported £23m.
"Chelsea Football Club has today brought Marcos Alonso back to the Premier League with the completion of the defender’s transfer from Fiorentina," the Premier League club announced on their website on deadline day Wednesday.
"The 25-year-old Spanish left-back is the first defender signed by Antonio Conte following the recruitment of a forward, a midfielder and a goalkeeper to his squad. He has signed a five-year contract."
Alonso said: "I’m very happy. It’s a step up in my career and I think this is the perfect place for me to continue developing. It’s time for me to win some titles.
"It was an easy decision for me to make when I heard the club were interested in signing me. My family and close friends know Chelsea is the club I have dreamed about playing for so I’m really excited about the challenge and I'm looking forward to working with my new team-mates."
