Barkley played his last game. Tarashaj, Niasse, Garbutt, Rodriguez won't make any difference they just won't play. Robles is as good as gone and is 3rd choice.
So the difference is Lennon, McCarthy and Besic I assume they will get some gametime in domestic club games. Bearing in mind they are not included in our EL squad last week...they will be sold very soon?
I can't see any of the three are leaving to be honest mate. They will be back up for our current 4 for 3 positions plus we don't have many wingers as it stands.
Siggurdson is replacing Barkley so he can be factored out of the squad.
Niasse for all intents and purposes is a back up striker for us right now. Until we sell him , the fact he is currently in the squad means he is an option. Is he good enough? Not really, but he proved he could do a job last season if worst came to the worst.
Tarashaj and Rodriguez may as well not be mentioned.
I'm not telling you are wrong mate, and some of the above probably support what you said. But considering we are aiming to have nearly 70 games this season at best, garbutt niasse and the rest will fill a gap if the squad is knackered
