4. Ezequiel Garay
As well as strengthening at left-back, United's new manager also needs to address his problems at centre-back, too. Rio Ferdinand will be 35 in November, while Nemanja Vidic has had his last two campaigns wrecked by injury, making just 25 league appearances since 2011. United do have able understudies for the duo in Chris Smalling and Phil Jones, while Jonny Evans is improving all the time, but the Reds still need someone to come in and add a bit of experience to the back line. One option there is Benfica powerhouse Ezequiel Garay. At 6ft "4, the powerful Argentinian is a physically imposing figure and carries with him a strong aerial presence from set pieces. He marshalled Benfica to the final of last season's Europa League, where his side lost out to Chelsea, and he could be lining up against the Blues one day very soon, if recent reports are to be believed. The
Express claimed earlier this month United had "reached agreement" with the Portuguese club over a £17.2 million deal.
