Look at the terrible Mertasker injury (Photo)

The captain of the Arsenal German protector, Per Mertseker, has suffered a crack on his right eye after a clash with the English defender of Chelsea, Gary Cahill.

He was forced to leave the field and replace the Bosniak Sead Kolasinac.

Mertseker started meeting from the first minute after more than a year out of absence due to multiple injuries.

But this injury doesn't seem to prevent the 32-year-old from appearing in the game against Leicester. /Periscopi/
