Alejandro Garnacho's new neck tattoo has attracted the attention of fans in recent weeks since his summer move from Manchester United to Chelsea.
Garnacho, 21, joined the Blues for £40million in August after falling out of favour under Ruben Amorim.
The Argentine endured a difficult relationship with the United boss and was part of the club's 'Bomb Squad' over the summer after Amorim told him to find a new club at the end of last season.
He has had a slow beginning to life at Stamford Bridge, making just two starts, although it was Garnacho's cross that led to Richard Rios' own goal during Chelsea's 1-0 win against Benfica on Tuesday night.
