First impressions of Mubama are that he doesn't have the same physical presence and strength as a Larin or a Stewart.
Of course it is very early days and I'm not writing him off to end up being a good signing by any means, but not having seen him play before, my feeling is he won't provide the focal point that we have been used to with the Larin/Stewart combo. So, perhaps we will need to adjust how we play a little when he comes on or starts. We certainly seemed to miss Larin when he went off today.
