Manchester United midfielder Michael Carrick would welcome Cristiano Ronaldo back to Old Trafford.

United and Paris Saint-Germain are both interested in a big-money move for the Real Madrid star amid claims he's unsettled.

"I haven't really given it too much thought to be honest with you," Carrick told Sky Sports.

"Listen, you don't need me to say, everyone knows what type of a player he is and how good he is and what a career he's had.

"It's not for me to get involved in whether he comes to Manchester United, whether he leaves Madrid or not, that's not my business at this moment in time.

"Of course, I was lucky enough to play with him. It was just a joy to work so close to him and see how he plays.

"We will see how it pans out over the next few weeks and months."
