Fleck returned from a hamstring injury at the weekend in the 2-0 win over Aberdeen at Ibrox.
Fleck said, when asked if the Rangers squad was strong enough to retain the SPL title: “I think it is.
“There are obviously going to be injuries and suspensions cropping up somewhere along the line but I think the squad is good enough and they all stick by each other as a team so we should be all right.
“Team spirit is what you need most and if you don’t have that then you don’t have much chance.
“But the boys will all fight for each other and hopefully try to win the league again.”
