The win was Inter's first out of three preseason games, having been held by Austrian club Wattens and going down 2-1 to Bulgarian side CSKA Sofia.

Inter had to come from behind to achieve it, after Jordan Allen was in the right place at the right time to put RSL ahead in the 18th minute. 

Inter defender Danilo D'Ambrosio leveled things up on the stroke of halftime, volleying home a pinpoint cross from new signing Caner Erkin, before Jovetic sealed the win in second-half stoppage time.  

The 26-year-old Montenegro international scored with a stunning back-heel in the 92nd minute, nutmegging RSL goalkeeper Lalo Fernandez.

Inter faces Paris Saint-Germain next up in the International Champions Cup on Monday.
