Borussia Dortmund chief Hans-Joachim Watzke cautioned Bundesliga players against moving to the Premier League due to their scheduling issues during the festive season.
Bundesliga teams are currently enjoys a five-week mid-season break during the festive season, while Premier League clubs emerge from a hectic schedule.
Former Bundesliga stars such as Kevin de Bruyne and Bastian Schweinsteiger are taking part in an English winter for the first time.
At the same time, ex-Dortmund boss Jurgen Klopp has overseen six Liverpool matches as his former club took a break.
Watzke said that there is more for players to contemplate when eyeing a Premier League move aside from good pay.
“The players are squeezed there, often like a lemon,” he said. “They are given hardly any rhythm in their game.”
“Professionals who reflect on something more than just what arrives at the end of the month in their pursue will take this into account when making a decision.”
Watzke does not believe the increased financial power of the Premier League has resulted in a higher standard of play.
“If you would judge on the amount of salary it would always be a difficult race to win [for the Bundesliga],” he added.
“But it’s not. I have watched a lot of Premier League football over the Christmas holidays.”
“I do not feel that the level is increased there, especially considering how the expenditures have risen.”
