Former Manchester City defender Jerome Boateng has criticised the English media for not allowing foreign players time to settle in the Premier League.
The Germany international left his homeland in July 2010 to join City from Hamburg, but only spent one season in England before heading back to the Bundesliga with Bayern Munich.
Boateng only featured 24 times for the Citizens in all competitions during the 2010/11 campaign as he struggled to adapt to life in his new surroundings.
The 28-year-old has gone on to become one of the best defenders in the game at Bayern and was named Footballer of the Year in his country last season.
Leroy Sane made the switch to the Etihad Stadium during the last transfer window after spending his formative years with Schalke, and Boateng warned his compatriot there will be no honeymoon period.
"As a player you have to function immediately in England. The reality is you really need time to settle due to the different style of football," the World Cup winner told Sport Bild.
"But you don't enjoy any honeymoon period with the English press, who are immediately on your case. That isn't easy for players.
"Some can handle criticism better than others, but some question what on earth am I doing here? Everything is terrible, even the weather. Many players are broken by this."
