Leicester City boss Brendan Rodgers says Caglar Soyuncu has been good for summer arrival Cengiz Under.
Under joined the Foxes over the summer to be united with Turkey teammate Soyuncu.
"They are brothers, aren't they," a delighted Rodgers explained. "Their friendship goes back a long time, playing in the youths in Turkey and in the national team.
"He has settled in really well. He has come into a real family club, which is the essence of the club, it's together and I think he has really enjoyed that.
"He is enjoying the intensity of the league, he's enjoying the happiness when we win, and in the changing room and he has adapted to our style. He's having to run more, he's having to press more, and that takes a bit of time to get used to. But he's doing very well."
