Stoke City midfielder Xherdan Shaqiri admits he struggled with the man-management of Pep Guardiola at Bayern Munich.
He only made 26 Bundesliga appearances in a season-and-a-half before Guardiola moved him on to Inter.
"He is a very good coach in terms of what happens on the pitch but his communication was not so good with me," he recalled to the Daily Mail of the Manchester City manager.
"In the end we won the title and I hope he can do it here with Man City, but it's a different league and a different team and this will be the hardest year ever in his career.
"You saw against Sunderland how difficult it will be for him.
'This league is more crazy than ever. The best players and the best coaches are all here now. It's amazing. This is a very tough league and we will see what happens for him."
