Paris Saint-Germain have reportedly joined the race to sign Chelsea defender David Luiz in the summer.

Luiz has been linked with a move away from Stamford Bridge at the end of the season, with recent reports suggesting that Barcelona are high on a list of interested clubs.

PSG are expected to allow defender Alex to leave in the summer and are eager to replace him with Luiz, according to talkSPORT.

Barcelona could be willing to offer as much as £22m for Luiz but PSG would be able to compete with a higher bid of their own.

Luiz joined the Blues from Benfica in January 2011.
