The Colombian forward struck twice in the reverse fixture but could miss the second leg due to a new injury sustained at the weekend
Radamel Falcao is a doubt for Monaco's Champions League meeting with Manchester City next week having sustained a hip injury in their 2-1 win over Bordeaux on Saturday.
The Ligue 1 side welcome Pep Guardiola's City to Stade Louis II on March 15 following a pulsating 5-3 reverse fixture at the Emirates Stadium in February.
Falcao, who has scored 22 goals for Monaco in all competitions this season and struck twice in the first leg, is now in doubt to feature in the European tie, though manager Leonardo Jardim remains hopeful he will be with his top scorer.
"He took a heavy knock to the right of his hip," the manager said. "We'll take a look at what's going on with it.
"I hope it's not a serious thing, just the one knock, but I have to wait for the scans.
"Today, we didn't risk starting him though he is feeling good at the moment.
"I hope the injury is not a serious one, because if he is fit, he will start against Manchester City."
