Arsenal boss Mikel Arteta admits he has burnout concerns for Bukayo Saka.

Saka has been a shining light for Arsenal this season, and he continued his fine form on Thursday by setting up two goals in the Gunners' 3-2 win over Benfica.

Asked if is it inevitable that Saka will have to be given a rest at some point soon despite how excellent his form has been, Arteta said: “At some point, ideally, yes.

“On Thursday night at some stages in the game we were thinking about that, because you can see it.

“It is not only him, there are a lot of players who have played so many minutes, you could see the Benfica players and you could sense the fatigue and the changes they had to do straight away.

“But obviously when things go well the energy that creates sometimes overcomes fatigue, and I prefer not to talk too much about fatigue.

“If we have to rest players, we have to rest them, because we have to keep them fit as much as possible but as well you have to develop that mental toughness that you need when you are in competitions you want to win."
