It's not a lack of depth Plym. Only a few weeks ago, Rooney was talking about getting a few players out on loan because they weren't getting any game time.
It's a bad run of injuries though I'll admit.
We have Mumba who can play in place of Cissoko and some might say he's better off playing there with an out-and-out defender at LB. That's more like the balance we have on the right when Edwards plays behind Whittaker.
We have Issaka who was possibly our best player against Leeds, giving their RB a pretty torrid first half and scored a very good goal in his first start for one so young.
We could try changing the formation with two attackers rather than three and being a little more sound defensively as a result.
We could go back to two No 10's (Al Hajj and Whittaker perhaps) behind a single striker. That's the way we played under Schumacher, with Azaz and Whittaker playing just like that.
Cissoko is only 21 after all and if you just read the papers you'd think he was a one man team. In fact in his first couple of games, he was a nightmare, over-playing and wasting good position after good position. To be fair to Rooney, he's sorted him out and got to be much more direct recently, hardly a step-over in sight, and much more dangerous as a result. But he's still learning and the sending off was a very good example of how he still has a lot to learn. If Issaka can play like he did against Leeds, then we won't be substantially worse off.
If you want to know who I'm most worried about being without, it's Lewis Gibson, whose been an absolute rock in every game he's played.
