Celtic have had a pretty busy summer transfer window in terms of acquisitions, bringing back a fan favourite in the defence, some youngsters to surround their core, and a quality veteran backup. While they have not yet made one of their big-money transfer additions, there is still plenty of time to go in the window and some high-profile names being linked with the Scottish champions. With that said, let's take a look at each addition so far that has been formally announced, and grade them based on fee, skill, positional need, and outlook. The grade for this move has to be a high one, predominantly because Celtic are landing a club hero on a free transfer. While Tierney has no doubt dealt with a litany of injuries in his career, especially recently, he has shown to be an exceptional performer in the Scottish Premiership and should be able to return to at least some resemblance of that form for the foreseeable future. With left-back also being a position of need for the club, this is an all-around strong move.
