Arsenal fans have noticed what Dinos Mavropanos did during national team duty on Sunday night.
The centre-back has spent this season out on loan at Stuttgart having only made seven Premier League appearances for the Gunners following his 2018 move from PAS Giannina.
Mavropanos made 21 appearances for Stuttgart this season as they finished ninth in Bundesliga, and that loan spell followed a short-term loan with Nurnberg last season, when he managed 11 appearances at the back-end of the campaign.
Meanwhile, the 23-year-old has also been busy representing his country with Greece taking on Belgium and Norway in international friendlies.
Greece won't be heading to Euro 2020 having missed out on qualification, but they have put in two impressive performances during the friendlies.
For the second of those games, Mavropanos slotted into the centre of defence as part of a back five, and he put in an excellent performance as Greece won 2-1.
During the friendly in Malaga, Mavropanos helped keep sought-after Borussia Dortmund superstar Erling Haaland quiet.
Haaland is being rated at around £150million ahead of this summer with a whole host of clubs reportedly in for his signature, but Mavropanos made sure he could not get on the scoresheet on Sunday night, while Martin Odegaard was also kept quiet.
Arsenal fans have been reacting to that performance on social media. Here is what they have had to say on Reddit.
lazy_summer_days - "Pocketed Haaland and deserves a chance to fight for his place here."
Chango6998 - "No sense in not giving him a go unless Stuttgart lay down some cash."
Nosorius - "Played really well apart from a missed interception in the last minute that the keeper just gathered anyway. He deserves a chance. Wenger trusted him for a reason."

Carterxix - "Deserves a chance during pre season honestly."
Arstlers - "I watched most of the game, he was really solid and played a lot of nice passes. Looks to have improved a lot."
Trytomovewithpurpose - "From what little I have seen he is pretty decent with the ball. I do hope he gets a chance at Arsenal. Would be silly if we have to net spend to sell him and buy a new CB."
Ankeiii - "Mavro deserves a chance but he been playing in a 3atb system(Stuttgart and Greece), not sure how well he works in a 2 CB pairing."
