The Germany international, who was part of his nation’s World Cup success in 2014, has long been hailed as one of the best playmakers on the planet, winning honours in his homeland with Bayern Munich before heading to the Bernabeu.
And reports claim that he’s a wanted man, with the Manchester duo, United and City, both keen on him.
Kroos worked under Guardiola for one season while the pair were at Bayern, but a reunion is seemingly on the Spaniard’s mind.
United have been aligned with Kroos throughout the past few transfer windows, and a move for the 26-year-old could boost their hopes of a Champions League return.
The midfielder won three Bundesliga titles, three German cups and the Champions League while with the Bavarian giants.
