Pep Guardiola desperate to sign a new left back before the transfer window shuts with David Alaba and Nicolas Tagliafico on Manchester City's radar - but any potential move depends on whether they can sell Aleks Zinchenko

Manchester City are working on landing a left back before Monday's transfer deadline, but a move is dependent on Aleks Zinchenko's future.

Sportsmail revealed last month that Pep Guardiola still had his sights on two players to bolster his ranks following their ambitious bid to sign Lionel Messi.

Ruben Dias has agreed a £64.3million switch from Benfica to add more physicality to the central defensive area – but Guardiola wants more by way of another full back.

The manager believes a freshening up of personalities in his squad could contribute to an uplift on last year's disappointing campaign.
