If selected, Torreira will become the first Arsenal player to take part in 25 games this season but there is little advantage in giving the 22-year-old a rest.
Matteo Guendouzi, just 19, is only one game behind him in what has become a baptism of fire in his first season in England.
Inevitably, that could lead to concerns of burn-out in such a young player but Emery joked that the France Under-21 international is the last player he is concerned about.
“I was speaking with Koscielny and before the Burnley game I asked him about the possibility of playing,” the Gunners boss recalled.
“He said, ‘Not today’, because he’s very tired after two matches in a week, and I decided for him not to be with the group. ‘I’m not Matteo’ Koscielny added. ‘Matteo is 19 and I’m 33 years old’.
“So I’m very happy with Matteo and he is improving a lot. He is helping us with the quality and the possibility to play our style.
“He needs to improve more and needs to continue his progress with us, but he’s very young.”
