#2 Thomas Meunier (Paris-Saint Germain)
Since joining from Club Brugge in 2016, Thomas Meunier has been impressive for Paris-Saint Germain. His exceptional performances for the Ligue 1 champions earned him a place in Belgium's World Cup squad, who finished third in Russia last year.
Despite being plagued by troublesome injuries, he has made 30 appearances (all comps) this term, with five goals and seven assists to date. As a converted winger, Meunier could prove a tailor-made replacement for Valencia, who too was originally played further forward at Wigan before being converted.
Meunier admitted in an interview that he supports Manchester United and would love to play in England one day. Having been linked with a move away from the French capital again this summer, this could present an opportune time for United to pounce and sign one of the world's best right-backs at a time of need.
At 27, Meunier would provide some much-needed experience within their squad and his presence could help to boost their credentials as a title-chasing side - that has appeared to be lacking recently for the Red Devils.
