Aye agree.
Though I honestly think we should prioritise (assuming no major outgoings other than Kev) a playmaker, a goalie and a right back.
As you said back up striker depends on progress of Niasse but we do also have Rodriguez and Tarashaj.
And top class centre mids are very hard to come by mate and are all at the best clubs. We have one in the making in Besic so I'd rather play him and McCarthy (who showed how good he is as a defensive mid on Saturday) together, with Barry as cover and Cleverley as the utility player.
Then make a move for a youngster like Cook who is already capable and won't cost the world.
The Tielmens shout is okay but he'd cost £20mil at least and tbh and I think we need other areas that need addressing first.
