The Chelsea FC defensive midfielder was captaining his side after the dismissal of Aleksandar Kolarov, but followed the left-back into the changing room soon after, for swinging his arm in the face of Portugal midfielder Andr Andr
Nemanja Mati has had a poor season with Chelsea FC, failing to keep up to the standards he set for himself with his performances in the first half of last season, as well as throughout the later half of the 2013-14 season.
Blues’ manager Jos Mourinho has substituted him quite a few times during the current campaign — a break from tradition — but did so in humiliating fashion against Southampton, after the Serbian spent little over twenty minutes on the pitch.
It seems as though that built-up frustration exploded on Sunday night against Portugal, as Mati swung his arm out quite deliberately at FC Porto midfielder Andr Andr , deservedly receiving a straight red card for the foolish challenge.
A video of the incident can be seen below.
