Saka injured his ankle and foot in the Gunners’ 5-0 win over Nottingham Forest on Sunday and was forced to retire before the half-hour mark.
It had raised fears that Saka could miss the World Cup, which is due to start later this month in Qatar with England facing Iran on November 21.
The winger didn’t seem too embarrassed as he left the Emirates Stadium on Sunday and toured the players’ lounge before heading home.
Arsenal manager Mikel Arteta was also relatively optimistic about Saka’s injury and, when asked if the 21-year-old playing at the World Cup might have any doubts, Arteta replied: “I hope not.
“It was a bad shot. From the start he was limping, but I can’t see any further than that.
“Let’s see how he is in the next few days.”
Asked if it was an ankle or foot problem for Saka, Arteta said: “I think he was kicked a few times and he wasn’t there. ‘easy.”
Arsenal were training on Wednesday afternoon ahead of their final Europa League game against FC Zurich at the Emirates Stadium. Zinchenko’s participation in training was also a welcome sign of his eventual return from a calf problem.
The Gunners are currently top of Group A and will secure first place, and a bye to the Round of 16, if they equal PSV Eindhoven’s result against Bodo/Glimt.
Arsenal are then in action on Sunday, when they travel to Chelsea in the Premier League, and Saka should not have been risked against Zurich.
