In the London derby, Arsenal fans showed unpleasant behavior towards Mykhailo Mudryk.

The 22-year-old Ukrainian stepped onto the field in the 71st minute and was booed by Arsenal fans from that moment on.

Adding to that, one of the fans, a 21-year-old man, pulled out a laser and began shining it at the promising Chelsea forward. It was announced today that the man using the laser has been arrested by the police on suspicion.

Arsenal fans remember the winter transfer window, when M. Mudryk was long linked with the Gunners. However, Chelsea showed ambitions and snatched the talented Ukrainian for 100 million euros.

The player himself showed more desire to join Arteta's pupils, but the Blues offered a more lucrative deal to the Ukrainian team.
