Stuttgart boss Pellegrino Matarazzo has praised Arsenal loanee Konstantinos Mavropanos.
The 23-year-old was moved out on loan by manager Mikel Arteta from the Emirates Stadium club.
But he is impressing with the German club in the Bundesliga, and the Greek international could even work his way back into Arteta's plans for next season.
Matarazzo is quoted by Football London as saying: "He's our gladiator! He's a monster in terms of physique.
"And when he makes a mistake, he hums around some Greek swear words.
"I like that. He's just a tough dog."
