Chelsea have announced the £35million signing of 21-year-old Monaco defender Benoit Badiashile on a seven-and-a-half year deal.
The Blues have been looking for a left-sided centre-back since the summer and were unable to agree a deal with RB Leipzig for the Croatian World Cup star Josko Gvardiol.
It was understood that Chelsea had reached an agreement to sign Badiashile earlier this week - and agreed personal terms for a long-term contract.
Badiashile then arrived in the capital and completed his medical before completing his transfer.
