Kelly missed both of England's matches against Belgium with a foot injury, while Russo withdrew after the opening game with an unspecified problem.

Goalkeeper Daphne van Domselaar was also injured while on international duty with the Netherlands.

Gunners head coach Renee Slegers described Russo and Kelly as "touch and go" for Tuesday's match, adding that Van Domselaar was "the same".

"It's a day-by-day thing - it's small knocks, so we'll have to assess it day by day. So, we'll see," she said.

"Tuesday might come too early, but then we'll have to reassess for Saturday (against Lyon in the Women's Champions League). But the focus is on Leicester."

However, Slegers added that her number one goalkeeper could be missing for up to six weeks.

"We assess day by day. It's looking positive and she's doing well, but at the moment, we're still assessing, getting specialists to look at it.

"We don't know exactly how long it will take, but on the long end, it could be six weeks, but she could also be back earlier."
