The 24-year-old has found his future the subject of much recent speculation, with rumours rife he could end his spell with Bayern Munich in the summer.
Kroos and Bayern seem to be having a major dispute over a new contract, and United were linked with a January move for the German playmaker.
And now younger brother Felix – who plays his football for Bundesliga outfit Werder Bremen – has revealed he has discussed the possibility of a switch to England with his brother Toni.
“We have already talked about it,” he told Sky Germany . “Manchester has been the team of my dreams since I was a child.
“However, I don’t give him any advice. He will take a good decision for himself. There are worse situations than having to decide something like that.”
It still remains unclear as to whether David Moyes will be the man tasked with signing new players in the summer however, with speculation surrounding the Scot’s future as United boss increasing since the 2-0 defeat to Olympiakos in the Champions League last week.
