Five stars whose value could soar at the World Cup, with Liverpool target & Arsenal’s probable new right-back

A strong World Cup from Kroos could propel him from one of Europe’s best players, into a genuine world superstar. The German midfielder is a superb passer of the football, and can dictate matches from the base of midfield. Manchester United want to make him their marquee summer signing, but know they’ll have to break the bank in order to do so – especially if he plays a key role in a German triumph.
