In an interview with Polish newspaper Przeglad Sportowy, Wojciech Szcznesny's father spoke about his son's recent performances for Arsenal and reports that he had been fined by the club.
Maiej Szczesny, himself a former goalkeeper, admitted that his son was at fault for Southampton's first goal scored by Sadio Mane on New Year's Day but went on to criticise Arsenal's first choice centre backs.
In particular he singled out Per Mertesacker for having "the agility of a rhinoceros".
...look at the Arsenal defence - how these guys are playing is a disaster, but for some reason, nobody pays any attention to it.
Laurent Koscielny should immediately have run to protect Wojciech, and Per Mertesacker should have stood in the goal. Unfortunately they did not do that and gave him zero support, and in that situation Mertesacker showed the agility of a rhinoceros.
Wojciech is often paying for it, and that he really cares. He needs someone who will critically analyse every game with him, but also remain positive.
Someone should support him, but the coaching staff at Arsenal are not doing that, meanwhile the entire defence this season is an embarrassment.
He also denied that the Arsenal goalkeeper had been caught smoking in the showers after the Southampton game.
What the British papers wrote about my son smoking under the shower after Southampton game, this is bollocks.
Maciej was no stranger to controversy himself. Here he is being sent off for attempting to strike Roberto Mancini during a 1991 Cup Winners' Cup quarter-final between Legia Warsaw and Sampdoria.
