I think Keepers are decent enough to keep. Nice balance.
I don't think C miller is strong enough back up alone for Tierney. So I voted to keep Izaguirre are experienced back up, both to help Miller and hopefully only sparingly cover KT, whom I hope is back to his best after op. But Hayes can also play left back if needed? Like wise I would keep Lustig if he wants stay, I have enjoyed his love of Celtic and although he isn't best RB dynamically, he has earned the shot at 10 IRA. Also the dude at RB on loan from dortmund wasn't any better than him. So his vice captain role and his general experience I like. But if funds are flush for new fancy dynamic RB them maybe let him go. I like him and that goal against Aberdeen to take lead made me fall in love with the big guy again.
No Idea about other two fullbacks, so maybe we are OK at fullback without new player?
I would definitely get shot of Compper and bring in a first team ready Captain type Centre Back to replace Boyata whom I assume is gone and controversially I would keep Hendry unless he wants to go.
I rate both Simunovic and Ajer. But I would like a 6 ft six monster of aCentre back to really add presence. Maybe 10 million and 40k wages.
I like the central mid field we have but I would like to add a real quality deep playmaker without losing any of the options we have no, assuming they want to fight for places. Again 10 million and 40k wages for the new star mid.
Think we are ok at attacking mid number 10 role.
I would punt Sinclair if we can, can't really see him getting it back for us, not sure he enjoys Celtic enough. I would drop French eddy into that Sinclair spot. With Hayes and Morgan fighting him for first team. With forrest and Shved on other wing. and release Benyu. With Johnston as back up/fringe
Leaves us with Griffiths and Bayo up top.
So I would like two 10 million strikers on approx 40 k to add to squad. One a very experienced Power house goal machine type. And a spare young striker ideally Weah type.
That would balance out squad and hopefully add goals from crosses and corners and free kicks.
so 4 new guys in 2 strikers, 1 centre back, and I centre mid.
allows option to play 442 as well as 4231 with number 10 in hole, 352, and 433. and even 4123.
Would add 4 top players to first team allowing McGregor to be first team utility man when brown and new quality cm on good health to hold engine in place.
