The most reliable football transfer source Fabrizio Romano just confirmed a few minutes ago that Brighton's Mac Allister is moving to Liverpool with personal terms already reached between Liverpool and the player. I think it is a great signing for Liverpool, they had a pretty bad season, and that's why they are starting their transfer business pretty early. Mac Allister will greatly improve their midfield, just as he did in Brighton and does for Argentina.
I think Mac Allister is just the beginning in order to restore the midfield. Fabrizio also reported that there are more names on the list like Manu Kone, Kephren Thuram, Gabri Veiga 
. I think that Liverpool are planning to sign lot of players and hence they are taking things fast here. Mac Allister is a great signing and that really makes the Liverpool midfield solid but they still need more options in midfield. I am glad that board are now listening to Klopp and signing some players to strengthen the squad.
What do you guys think about this move, both for Liverpool and the player himself?
I think the move is perfect
for Liverpool. Remember that there were strong interests of Liverpool on Bellingham and Bellingham has established himself as kind of a modern midfielder with everything in terms of defensive and offensive attribute. As for Mac Allister, I feel he is a player who was too much underrated until the World Cup and he is kinda similar to Bellingham in midfield. Although he might play a bit different but I get the feeling that he is kind off similar to Bellingham. So if you ask me how good it is for Liverpool, then I will say it is perfect and a very very smart move keeping the budget in mind
especially when you think that they were going for Bellingham at one point.
As for Mac Allister, he is now representing a great team and chance to improve himself under Klopp and is a very crucial step in his career. There will be pressure on him, but he has to take those chances in order to progress. Reports are that it will be contract until 2028, so he has good amount of time at Liverpool here.
