Interim manager Guus Hiddink has suggested that Alexandre Pato is unlikely to make his Chelsea debut against Watford tomorrow night.

The Brazilian joined the Blues on an initial six-month loan deal from Corinthians last week.

However, having not played since November, Hiddink has revealed that the 26-year-old is not in the best physical condition.

"I don't know if he's up to the game. He's in preparation and not fully fit," Hiddink told reporters.

"The paperwork is done and he's available. It's another thing physically and mentally. We have to prepare him well."

Pato will wear the No.11 shirt during his time at Stamford Bridge.
