Saka went off injured during Saturday’s 4-0 win at Bournemouth with Jesus also picking up a knock late on, but both trained with the rest of the squad on Monday morning.
Arsenal face Lens in the Champions League on Tuesday and then play Manchester City in a Premier League showdown at Emirates Stadium on Sunday.
Saka appeared to hurt his foot when blocking a shot from Bournemouth left-back Milos Kerkez and his fitness will be a relief for Mikel Arteta.
Arteta insists he will not take his eye off Lens, ahead of Sunday’s clash with Manchester City.
After City suffered a shock 2-1 defeat at Wolves on Saturday, the game this weekend gives the Gunners a chance to make a real statement about their title ambitions.
