Aston Villa's Youri Tielemans has urged Paris Saint-Germain supporters to "stick to football" if they taunt goalkeeper Emi Martínez during Wednesday's Champions League quarterfinal clash after the Argentina No. 1 travelled to the French capital wearing a baseball cap highlighting his 2022 World Cup triumph against France.

Martínez has been an unpopular figure in France since helping Argentina win a penalty shootout in the World Cup final in Qatar. The 32-year-old's antics during the shootout and after the game were deemed to be disrespectful by the French and he also angered Lille supporters by shushing them after helping Villa win a Conference League penalty shootout against the Ligue 1 side last season.

The former Arsenal keeper did little to ease tensions with French fans by boarding Villa's flight to Paris with a cap bearing a cockerel -- a French national emblem -- alongside the Argentina flag and the four international trophies he has won with the world champions.

But midfielder Tielemans played down Martínez's dress code and said the Villa players have no issue with the PSG fans targeting their goalkeeper -- so long as they keep any criticism to football rivalry.

"It's probably his style," Tielemans said about Martínez's cap. "All I can say is that he is ready for the game tomorrow and he hasn't spoken anything differently. He's looking forward to it.

"I don't care [about the reception he gets]. Whatever happens with Emi, as long as it stays in football terms, I don't mind."
