Julian Draxler is not best pleased - believing he had a goal chalked off after it was viewed on a 'video-cube'.
Arsenal have been heavily linked with a move for Julian Draxler in recent months.
The German international, who has a reported release clause of £37 million, was heavily linked with a move to the club in January is also said to be attracting the attention of Bundesliga rivals Bayern Munich.
However the Bavarians recently ruled themselves out of a summer bid for the player - and now it seems Arsenal are the favourites to snap him up in the summer - if he decides to leave Gelsenkirchen.
On Friday he was in action against Eintracht Frankfurt - a game that the Royal Blues dominated and won comfortably, 2-0.
But for Draxler there was certainly a disappointing moment in the game - as he saw what would have been his second goal in the Bundesliga this season and his first since netting in November.
Schalke were already 1-0 up when Draxler smashed the ball underneath Frankfurt goalkeeper Kevin Trapp.
The goal was originally given - but referee Christian Dingert then decided to converse with his assistant on the matter - which is where the controversy comes in.
As while the two officials were chatting the goal came up on the massive ‘video cube’ in the centre of the pitch - which clearly showed Draxler in an offside position.
And Draxler believes that the referee only gave the decision after, for want of a better word, illegally using video technology.
"Suddenly, the referee raises his arm, because he probably recognized on the video cube my offside."
But in Germany, unlike Britain, the referee can actually talk to the media - and Dingert has, putting Draxler in his place as a consequence:
"My assistant saw from the sidelines basically an offside position and radioed to me. I ran to him and said that the ball was extended by a Schalke player to Julian Draxler, and then decided to offside. We have not assessed the situation on the video cube, we must not. "
What it matters I am not sure - Schalke won the game 2-0 and Draxler genuinely was offside.
It just seems this Draxler kid loves a good moan.
