Atletico Madrid boss Diego Simeone has revealed that he would be "open" to the idea of signing a replacement for the injured Tiago.

The 34-year-old is expected to miss the next three months of the season after fracturing his leg in Saturday's La Liga clash with Espanyol.

Simeone has talked up the players that he currently has at the capital club, but admits that he could be active in the January transfer window.

"Clearly it's difficult to find another Tiago because at 34 he has the ability and experience that a 26 or 27-year-old doesn't have. I'm convinced he will return before the end of the season because we're hopeful and we need him back," Simeone told reporters.

"We'll work with the lads available. There's Koke, Saul [Niguez] and [Matias] Kranevitter, who is coming, and also Gabi and Thomas [Partey]. I see more competition [in central midfield] than going forward. We'll see who does the best for the team.

"When the [January market] comes, we're always open to any scenario. This time is no exception, enhanced by Tiago's absence."

Tiago underwent an operation to repair the damage on Monday, but is not expected to be available for selection until at least March.
