Jenas believes a top-form Morrison will go hand-in-hand with Rangers promotion push.
"I thought Ravel was exceptional against Charlton," Jenas told the Fulham Chronicle. "I wouldn't agree he's taken time to settle in.
"Leeds were a physical side doing everything they could to stop him, and I think he's settled in straight away.
"He was at Manchester United - and he had to leave; he was at West Ham - and he had to leave.
"Those reasons are beyond us.
"All we can to get the best of Ravel while he's at QPR and if we do we stand a better chance of going up."
