Arsenal were one of the more active sides during the January transfer window and the addition of Henrikh Mkhitaryan could be looked back on as one of the signings of the season.
The Armenian international joined in part-exchange for the unpopular Alexis Sanchez and the Gunners side that played against Everton this past weekend looked to be much freer on the pitch.
It would be simplistic to suggest it was entirely down to Mkhitaryan and fellow new signing Pierre-Emerick Aubameyang, but they clearly had a positive impact on the squad.
This level of performance will have to be displayed on a more consistent basis before supporters get too excited about this representing a new dawn for the club, but the first signs were encouraging.
Arsenal played Everton off the pitch and were out of sight by half-time. The match finished in a comfortable 5-1 win for the home side.
Although it was a disappointment not to keep a clean sheet, the side were near perfect throughout and that gives them something to build on heading into the closing months of the season.
It was a surprise when the rumoured swap deal involving Sanchez and Mkhitaryan eventually went through.
In the modern game, it is rare for straight swap deals to happen and it is even less common for it to involve two clubs that have been fierce rivals in the recent past.
The majority of the coverage suggested that it was a far better deal for Manchester United and it was seen as a sign of weakness from Arsenal.
Considering the form of the two players since arriving in England, that is a difficult viewpoint to argue against.
However, the Gunners will have seen the appeal of signing an experienced international and his first start indicated that he could be a huge success in North London.
The former Borussia Dortmund player made an immediate impact and contributed three assists during the match.
Manchester United had signed him in 2016 to add creativity to their ranks and although he threatened to do that at times, he never found his stride at Old Trafford.
It can be argued that his performance against Everton on his Arsenal home debut was the best of his Premier League career to date.
Given it came just weeks into his career in North London, there is reason to be genuinely excited about what he can achieve in a Gunners’ shirt.
Mkhitaryan was most dangerous down the right-wing, as he twice got free and supplied good balls in for two of Aaron Ramsey’s goals.
However, one advantage of playing him in a front three with Mesut Ozil, Alex Iwobi and Aubameyang was that he could interchange positions as the game progressed.
His second assist came when he moved into a central area and played a nice through ball to the striker he regularly supplied at Borussia Dortmund.
Their previous relationship has allowed both to settle quickly into the Arsenal team and the benefits were there to be seen on the weekend.
The Armenian played only three key passes, which is a surprise considering his influence on the game, but those that witnessed the whole match will attest to his quality.
He looked a completely different player to the one that was devoid of confidence at Manchester United.
In addition to creating several chances and making three goals, Mkhitaryan came close to scoring himself.
He popped up on the right wing in the first half and cut inside before producing a powerful effort that went just wide of the post.
Jose Mourinho was reluctant to give a prominent role to the attacker at Old Trafford as he had doubts about Mkhitaryan’s defensive work.
However, that part of his game was very impressive against Everton, as he won four aerial duels and completed seven ball recoveries.
He attempted 10 tackles in all and was successful in less than half of them (four), but he showed a willingness to work hard and that will have pleased Arsene Wenger.
The next challenge for Mkhitaryan will be to find the consistency that alluded him during his time in England so far.
He has shown flashes of his ability, but he hasn’t lived up to his reputation and his confidence levels dropped as a result.
His home debut should have provided him with plenty of that and it is crucial that he uses that to motivate him over the rest of the season.
If he can maintain this high level, Arsenal will have the player that Manchester United had hoped they were getting when they signed the Armenian.
