Chelsea winger Joe Cole big fan of Portsmouth boss Grant
Grant took Chelsea to the Champions League final in 2008.
"I am very fond of Avram," said Cole.
"He is a great manager. Maybe when he took the job over, coming in after a very popular manager in Jose Mourinho, made it very difficult for him.
"But he proved himself here and took us within a whisker of winning the Champions League - better than any other manager has done at Chelsea so far.
"What he's done at Portsmouth is remarkable with all the turmoil that's going on, the players there really seem to have responded to him."
