I think evolution rather than revolution is more important this summer than ever. The condensed season next year with the season starting a week earlier is going to make it more important to hit the ground running and with the disruption caused by a winter world cup, it could be useful to have a squad that is largely familiar with each other and our tactical approach so they slip straight back into a rhythm after the winter break.
In addition to that, I think we already have a good core in Wright, Baath, Evans, Pritchard and Stewart who I think will be comfortable starters at that level. Then we have youngsters who we want to develop in Neil, Embleton, Cirkin, Patterson, Huggins and Matete so we don't want to sign too many players in front of them that may harm that. Finally, we have players who are good characters and versatile options in Gooch and O'Nien.
Personally, I'd take up our option on Roberts, sign Broadhead and bring back Clarke on another loan as well.
That's 16 players for the squad already (with very low outlay), meaning we can pay for quality rather than quantity. Here's what I'd like:
An experienced goalkeeper with an eye on a coaching career that Patterson can learn from and provide a bit of competition - Dream signing is Ben Foster but unlikely.
A first choice Right back is probably the main focus in defence for me. Loan out Hume and allow Huggins to compete/cover both full back spots.
Another central defender, ideally with a bit of pace - Dream signing is Dion Sanderson.
Another addition to the midfield, someone with experience who can help to control a game - Dream signing is Conor Hourihane
A forward who is versatile and can play off the wing if needed. We need someone who can play up front but it's a challenge to sign someone of Championship quality who will sit behind Stewart and possibly Broadhead. Scully, Twine or Andy Weimann would be good options here, though I don't know if the latter 2 have realistic price tags.
