The 28-year-old Colombia international had not played since rupturing the anterior cruciate ligament in his left knee during a French Cup game against amateur side Chasselay on January 22.

The injury cut short his debut season at the big-spending Ligue 1 club and prevented him from appearing at the World Cup, where Colombia reached the quarter-finals.

Falcao replaced Dimitar Berbatov with 18 minutes to play at the Emirates Stadium, taking up a central role alongside Valere Germain in a 4-4-2 system, but did not manage any attempts on goal.

The match was the opening game of the Emirates Cup pre-season tournament, which also features hosts Arsenal and Benfica.

Monaco took the lead in the 30th minute when Joao Moutinho's left-wing corner was met by Aymen Abdennour and flicked into the net off Ruben Vezo for an own goal.

A Ricardo Carvalho own goal six minutes later levelled the scores and Valencia went in front 20 minutes from full-time when substitute Paco Alcacer tapped in a low cross from Aly Cissokho.

But after Falcao had made his entrance from the bench, Lucas Ocampos struck an 80th-minute equaliser for Monaco, running from deep and planting a shot in the bottom-left corner from outside the box.

Monaco, runners-up to Paris Saint-Germain last season, open their Ligue 1 campaign at home to Lorient a week on Sunday.

Valencia's season does not begin until August 23, when they visit Sevilla in La Liga.
