Arsenal are wearing their blue third kit for their Europa League game against Rapid Vienna instead of their traditional red kit, despite being the home side.
The decision was made because the white in their home strip is a clash with the visitors’ home kit and the red is a clash with Rapid Vienna’s away kit.
As a result, the Gunners have had to wear their dark blue third kit.
In their most recent Premier League game against Wolves there was another bizarre kit situation, with Bernd Leno not allowed to wear the traditional green goalkeeper shirt because of a clash with his opposite number.
Rui Patricio also wears green for Wolves and Premier League rules dictate that there can be no kit clash, even for goalkeepers.
Leno was also not allowed to wear Arsenal’s other goalkeeper kit because the black clashed with the referee and the German instead wore the Gunners’ white outfield strip.
Speaking ahead of the game against Rapid Vienna, manager Mikel Arteta addressed his side’s lack of goals.
“Well, there are many factors, if you compare the Premier League with the Europa League, it’s different,” he said. “If you look in the last few years, how the team has shared the goals in the Premier League, it’s been quite limited.
“That’s not an issue that is happening now, it’s an issue that’s been happening for years. That has to be resolved. To put almost 80 per cent of that responsibility on one man is not fair.
“As a team, we have to resolve that. As a team, we get into a lot of situations and sometimes the service is not right, sometimes the timing is not right, sometimes the last execution is not right but as a team there are certain things that we have to do better.
“Again, it’s coming from a long way. We’ve been winning matches producing similar numbers but we’ve been very efficient. That sometimes is a state of energy, a state of mind, a state of confidence that you are doing everything right.
“When it gets to the moment you hit [the ball] and it doesn’t hit the post, and if it does hit the post, it goes in. That’s the difference. Football in the end is about the cohesion and the energy and belief of the team.
“When you lose games that gets touched and that’s one of the beauties of this sport, how you react against that adversity.”
