Shakhtar Donetsk coach Mircea Lucescu says David Moyes is struggling at Manchester United due to his rotations. Shakhtar host United tomorrow night in the Champions League.
"There will always be a change of philosophy under a new coach and every coach needs time to work in a proper way," Lucescu said. "This is why David Moyes is facing difficulties at this stage.
"But we have analysed the United games and of course we noticed there are always changes in the squad, maybe four or five players (each time).
"This rotation means the links between the players can be affected and I think turnover can cause a lot of problems sometimes. We have also discovered that here.
"The other big teams in the English championship, such as Chelsea, Liverpool and Arsenal, are not rotating the team as much as United and maybe that is a factor.
"We know the work of Mr Moyes from Everton, though, and he is one of the strongest coaches in the Premier League.
"He needs some time to work with his players and let's hope the team finds a good pattern after tomorrow night."
