Barcelona goalkeeper Marc-Andre ter Stegen did not realise what he was getting himself in for when he congratulated Arda Turan on his 13th goal this season.
Ter Stegen was clearly delighted with his team-mate's achievement, but may regret his request that Arda shave his beard when he reached 20 goals.
The attacking midfielder replied in kind, agreeing that he would shave his trademark beard off, but only if Luis Enrique's club lifted the Champions League, and on the proviso that Ter Stegen follow suit by shaving his head.
13 goals scored, congrats man ! you shave the beard if you score 20? https://t.co/Qb7OnhviVg— Marc ter Stegen (@mterstegen1) January 27, 2017
To win the Champions League, Barcelona need to overcome PSG in the last 16 of the competition. The Parisiens host Barcelona on February 14 before travelling to Camp Nou on March 8.
