Mikel Arteta has hit back at anyone questioning Bukayo Saka's commitment to England by insisting he would "send an MRI scan" to prove the winger was injured during this month's international break.

Saka was one of 10 withdrawals during England's recent UEFA Nations League double header against Greece and Republic of Ireland, a situation which captain Harry Kane described as "disappointing" before suggesting that "it's a tough period of the season and maybe that's been taken advantage of a little bit."

Saka was unable to complete Arsenal's 1-1 draw at Chelsea prior to the international break due to a thigh problem but capped a fine individual performance as he opened the scoring in Saturday's 3-0 win over Nottingham Forest at Emirates Stadium.

After Thomas Partey and teenager Ethan Nwaneri -- with his first Premier League goal -- completed the scoring in a comfortable win, Arteta defended the contrast in Saka's absence for England and fine form for Arsenal.

"Well, we can send an MRI scan, it's very simple," Arteta said. "That's a communication that was very clear between the medical staff of Arsenal and the England national team.

"He hasn't done anything, he was away and needed time to heal. He's done one training session."

Arsenal secured their first league win since Oct. 5 to generate some positive momentum ahead of a difficult week which continues with Tuesday's Champions League trip to Sporting CP.

"I sensed a great energy in the last 48 hours," Arteta said. "The way everybody came back, I sensed a great togetherness and desire to change the situation and what has been a different period for us with all the situations that we had to come across. And the team is there straight away from the beginning. It was a flow, it was a dominance, there was an enthusiasm about it. That is what I demanded."
