​Manchester City's Nicolas Otamendi is being lined as a potential transfer target for La Liga leaders Real Madrid.

The Daily Mail is reporting that the Spanish giants are looking at Otamendi as a replacement for Portugal defender Pepe, who is reportedly moving to Chinese side Hebei China Fortune, ending a ten-year spell at the club.

Otamendi has endured a mixed spell at City since joining from Valencia in the summer of 2015. He has made 81 appearances for the club, winning the League Cup and helping his side reach the Champions League semi-finals for the first time last season. 

However, some City fans have never been fully convinced of his abilities as a defender and see him as a liability at centre-back.

City boss Pep Guardiola is also thought to be sceptical of Otamendi's defensive attributes and has reportedly drawn up a list of defenders he wants to go for in the summer, with Virgil van Dijk and Aymeric Laporte among the names mentioned.

Although Otamendi's representatives are believed to have already opened discussions with Real Madrid over a move, the Argentinian is not the only defender the Champions League holders are targeting, with Otamendi on a list of names being looked at by Madrid.
