Danny Simpson has backed former Leicester City teammate Harry Maguire to improve either Manchester United or Manchester City.
The centre-back has reportedly told his teammates that he wants to leave the King Power this summer.
He told talkSPORT: "I'm not surprised that United and City are in for him. For me he's one of the best defenders.
"He's a top lad and he's only going to get better. He's improving, he's a leader and he can be wherever he wants to be.
"The way he brings the ball out from the back and organises everyone is quality.
"He wants to go all the way to the top and I think if he does go to one of those two teams, he'll kick on straight away and take it in his stride."
