We do need a striker but for me it is our midfield which is the weakest part of our team. That midfield for me is Gueye, Gomes and Sigurdsson who have played together far more than any other combination and they seem to be getting progressively worse with each game.
Without being brilliant we do offer a reasonable attacking threat in Walcott, Richarlison, Lookman and Bernard.. they have pace and a good deal of creativity, add a striker and I think they could be formidable.
The defence has been poor but a defence is reliant on the cover given by the midfield in front of it and that has largely been non existent.
At this point I would accept McCarthy and Schneiderlin being given a run in the team on the basis that they can hardly be any worse than what is already there.
Putting Schneiderlin back in the side just sends out all the wrong signals to me. I’d rather not bother, that is such a backwards step. McCarthy was a decent player once and if he could get to his best levels again then you would have to consider him. At least you will get a bit of spirit out of him and he won’t hide.
