Bayern's Mats Hummels reignites talk of Manchester United swap

Bayern Munich defender Mats Hummels is looking at a transfer to Manchester United over lack of playing time with the Bundesliga champions, according to reports.

The Sun, citing German outlet Bild, says the Germany international is buckling under Bayern coach Niko Kovac's rotation policy. Hummels reportedly turned down a transfer to Old Trafford in 2014 while he was with Borussia Dortmund before making the switch to Bayern.

The Germany international, who was part of Joachim Low's squad in Russia that failed to advance from the group stage, has played in only three of Bayern's Bundesliga matches this season, but he scored in their Champions League win over Ajax this week.
