With Fabio da Silva supposedly off to Benfica next season, Ezekiel Fryers' future up in the air and Patrice Evra declining, Manchester United look set to sign a left-back in this summer's transfer window.
It has been something of a problem position for the Premier League leaders this season, with 30-year-old Evra the only experienced and healthy option on the left side of defence.
And it's clear the lack of competition for his place in the team has affected his performances significantly, with misguided tackles, a lack of tracking back and some poor crosses going forward symptomatic of the Frenchman's campaign.
Fabio and Ezekiel "Zeki" Fryers are both too inexperienced at the moment to provide real competition, so it's highly likely Sir Alex Ferguson will sign a left-sided defender to make that slot in the team a competitive one ahead of the new term.
Here are five left-backs who fit in with Manchester United's style and can cope in the Premier League and could become regulars at Old Trafford next season.
