Tottenham boss Jose Mourinho admits they'll have to wait to see Gareth Bale in action.

The Welshman is suffering with a knee injury sustained on international duty, and is facing a month on the sideline.

Tottenham were aware of Bale's injury prior to signing him on a season-long loan in a deal worth £20million last week.

But Mourinho admits after a closer assessment the club is no closer to knowing when the 31-year-old will be ready to play.

"I don't know when Gareth can be back," said Mourinho. "The only thing that I know is that the motivation is high, he is so happy to be with a club of his heart.

"When a player has this motivation, many, many times you can shorten the period of recovering and getting fit."
