Sead Kolasinac made a notable debut for Arsenal, coming off the bench to score a celebrated equaliser before going on to win the FA Community Shield - prompting fans to be very pleased with their new man.
The left-back played his entire senior career at German side Schalke, before not renewing his contract and signing for the North-London club.
Value For Money -
The fact Arsene Wenger was able to complete this deal on a free transfer is remarkable, especially considering the astronomical prices being quoted and implemented in the current market - such as Manchester City's £50m+ (as reported in The Guardian) for Benjamin Mendy who plays in the same position and is of a similar age.
Ultimately, it is footballing reasons that are most important - and there are many benefits to acquiring the 24-year-old's signature in that regard too.
Age & Experience -
The Bosnia and Herzegovina international has experience in the game, having already been capped 18 times by his country and featured in 23 European matches (including nine in the Champions League) for Schalke - and at 24 is a good pedigree for someone who hasn't even begun to peak.
Primarily used at left-back, Kolasinac is also adept at playing on the left side of a back three as demonstrated against Chelsea in the Community Shield.
Whilst his capabilities have been tried and tested in defensive midfield, he is also is effective at wing-back in a three or five man defence too, a formation that Wenger favoured greatly in the latter stages of last season and started with again this campaign.
Such dexterity is vital for a club playing in four competitions and hence playing so many matches in a season.
Above all else, the player needs to be good enough, especially at a club like Arsenal. Being named in the Bundesliga Team of the Season in 2016/17 certainly presents an argument for that case.
Noted for his excellent delivery (notching five assists in the league last season) and defensive solidity, he will be a welcome addition to The Emirates.
