Arsenal defender Stephan Lichtsteiner says he will retire from the game if he doesn't think he can perform at the top level anymore.
The Switzerland international moved from Juventus to Arsenal this summer although so far in 2018-19 he's made just one substitute appearance for the Gunners, with Hector Bellerin first choice under new manager Unai Emery.
Speaking about life at his new club, Lichtsteiner said he will be ruthless when considering his future in the game, per Sportal (h/t Liam Prenderville of the Daily Mirror).
"I was looking for a demanding challenge in a new league," he said.
