Manchester City have signed left-back Benjamin Mendy from Monaco on a five-year contract, the Premier League club said on Monday.

The 23-year-old France international is manager Pep Guardiola's third major defensive signing in the current transfer window following his purchases of Kyle Walker from Tottenham and Danilo from Real Madrid.

No financial details of the deal were disclosed, but British media reported that City paid 52 million pounds.

"I am absolutely delighted to be joining Manchester City," Mendy said on the club's website.
