"He is a very destructive player and a game changer. He can change things around very soon for his team. I want him to start performing soon, but after our match against KKR," said Irfan.
Yusuf, who was bought by KKR for USD 2.1 million, is yet to justify his price tag as he has scored a dismal 48 runs from nine matches this season, averaging a poor 6.85.
"It is a good sign for KKR that they are putting up a great performance without Yusuf being in form," said Irfan on the sidelines of a promotional event here.
Irfan feels that Daredevils, who are at the top of points table, would have to guard against complacency when they take on Gautam Gambhir-led KKR.
"We are at top and they are at number second position. They are playing good cricket and it would be an exciting match. There is no room for complacency," he said.
The Baroda player added the presence of Delhi players in KKR's squad would be an advantage to them.
"They have players who play for Delhi and that would definitely make things easy for them as well as they can exploit the conditions well. And for us we would try and keep our winning momentum on."
