Real Madrid striker Karim Benzema has heaped the praise on boss Jose Mourinho ahead of Wednesday's trip to Borussia Dortmund.
Benzema initially struggled to make an impact at the Bernabeu before Mourinho arrived in 2010, but the Frenchman has since established himself as a star at Real.
The former Lyon striker has paid tribute to the former Chelsea boss, who he feels has been a key factor in his success with the Spanish giants.
"The coach made me work a lot on the mental part of my game. I am now stronger in this respect," Benzema explained.
"I have had many ups and downs since I arrived in Madrid, but I am still here. Mourinho is a great coach, and he is supporting me."
Real have picked up maximum points from their opening two Group D games, while Dortmund are also unbeaten having seen off Ajax and secured a draw at Manchester City.
Benzema is 6.50 to score first on Wednesday night in Germany and Real are 2.10 to grab the win.
Dortmund are 3.40 to see off Real and Benzema is wary of the Bundesliga champions.
"Dortmund are a good team," he added. "They fight every year with Bayern (Munich) to be first in the Bundesliga."
