Jose Mourinho refused to rule out the possibility of Manchester United signing Mesut Ozil from Arsenal.

Ozil's contract with Arsenal expires in the summer.

Mourinho previously hailed Ozil as "the best No. 10 in the world."

When asked directly whether he will try to sign the 29-year-old, Mourinho mischievously replied with a smile: "No comment."

Ozil has yet to make a decision about his future and is open to a new contract with Arsenal.
