Atletico File Official Complaint Against Arsenal Hours Before Champions League Clash

Atletico Madrid have reportedly filed an official complaint against Arsenal ahead of their UEFA Champions League clash.

On Tuesday night, Spanish La Liga giants Atletico will take on Premier League leaders Arsenal in the Champions League at the Emirates Stadium.

The Gunners are looking to keep their 100% record alive, having beaten Athletic Club and Olympiacos in the previous two fixtures.

Meanwhile, Diego Simeone's men are hoping to win in England at the second attempt, after losing to Liverpool at Anfield in the opening round of matches.

Before the clash, it had been claimed that Atletico had filed a complaint against Arsenal.

As reported by The Sun, Atletico complained to UEFA after being left with cold showers at the Emirates Stadium.

Spanish news outlet MARCA stated that Atletico were left 'furious, surprised and confused' that a modern stadium like Arsenal's would lack such a basic requirement.

It has been suggested that Atletico alerted Arsenal regarding the hot water issue at 6:45pm, moments after their training session began.

Although the training session was due to finish at 7:30pm, the Atletico stars reportedly returned to the dressing room at 7:15pm, to find that the issue had not been fixed.

According to The Sun, hot water was restored by 7:25pm.

However, the report claimed that Simeone's players opted to leave on the team bus and shower at their hotel instead.

In response, Arsenal apologised to Atletico and stated that the problem had not occurred previously.

SPORTbible has contacted Arsenal for comment.

Speaking ahead of the match, Gunners boss Mikel Arteta heaped praise on Simeone.

He said: "At the highest level, I think what he's done since he got to Atletico has been outstanding, not only what he has achieved but the way he's done it.

"I think the identity that he has created for the club, for the team, the spirit, I think they are very simple and clear to identify, and that's because the manager is very much them."

Arteta added: "That's extremely difficult to achieve for a short period of time and to do it for 14 years, I think he's been there now, he's done something incredible so it'll be a pleasure to meet him."
