There were a total of nine arrivals at Celtic during the summer, with a few of the previous season’s players signing permanent deals.
It was vitally important that the club retained all three players as they provided different qualities that were needed for the team.
Before the window opened, both players were not Celtic players, so a case can be made for Carter-Vickers being Celtic’s most important signing of the summer due to the stability he brings to the defence.
It was evident to see how big a miss he was in the games that he didn’t feature in this season, and it is a testament to him as a player that he was given the captain’s armband in the absence of Callum McGregor.
Sead Haksabanovic looks like a player with real potential who will likely kick on in the second part of the season, which may also be the case for Aaron Mooy, who is impressing for Australia at the World Cup, as well as Oliver Abildgaard, who hasn’t featured too often.
A few of the other summer recruits have been important players for squad rotation, such as Alexandro Bernabei and Benjamin Siegrist, with there being a huge emphasis put on Moritz Jenz with Carl Starfelt missing a lot of game time due to injury, meaning that without him, Celtic would have been left short at the back.
Ange Postecoglou has already added Yuki Kobayashi to his list of recruits for this season, and there is likely more to come.
