I agree that we have other positions that aren't perfect, but if we play a 4-4-2 then it really is that whole midfield 4 that needs the attention. That group is barely serviceable....
Yes, our keeper can give us fits, our right back is getting old and his presumable understudy has only gotten real time in Germany, while we wish we had two standout center halves rather than one who is okay when not asked to do too much, one who spends too much time injured and one who, while very promising, is not quite top class. If reports are to be believed we have promising youngsters in Gibson and Branthwaite. Our left back is solid to very good depending on the day. We should have no complaints, for once, about the 2 playing up top as both are good and only going to get better.
Could some of those positions be improved upon - of course. Are they dire, not like the middle 4.
The middle 4 is woeful.
Our wide players offer next to nothing. Iwobi may come good then again more likely he won't, Walcott is past it (though perhaps a serviceable sub at a reduced wage), Bernard is a luxury player that we don't have the luxury of having, and young Gordon is young - though admittedly promising.
Our central players are crap or injured. Gomes not fully back (or worse just damaged), Gbamin is perma crocked (feel poorly for him), Gylfi seems to have lost it or mailed it in since getting married, Davies is a bench player at best and Delph seems to not be bothered.
1 wide player and 2 center mids is the minimum. For me Delph, Bernard and Gylfi have to be on the block to be sold and if a good offer comes in for any of the rest of the middle 4 - barring Gordon - we have to seriously consider it.
