The 23-year old attacker is being heavily linked with a winter move to Liverpool and Benitez has added fuel to that fire by playing coy on a potential Stamford Bridge departure.
"He was training with us yesterday," Benitez told the Fulham & Hammersmith Chronicle. "But that was just one training session. So now we have to wait, because he was injured.
"To be fair, I only saw him three times last week, so he couldn't train too much in this time with him.
"We will see. You never know in the market."
