Radamel Falcao will be playing for Monaco next season, after enduring two difficult seasons in the EPL.
The Colombia international spent a year with United, and managed only four goals in 29 appearances.
His career went further downhill following another disastrous campaign with Chelsea, hindered by injuries, resulting in him missing out on the Copa.
“Monaco made a big investment in me and they want some return on that. They want me back at the club for next season,” he told TYC Sports.
“I need to have minutes, to play, and we’ll see what happens. Monaco want to see what my position is in a year, to see what possibilities I have.
“The project changed, it took a turn in every sense. Today they’re more of a selling club than they were three years ago, when they wanted to put a very strong team together.
“In principle, the idea is that I’ll be with Monaco for that season.”
Falcao says he rejected enquiries from clubs in China and South America in the mid-season transfer window as he is holding out for a return to River Plate in future.
“It looks very difficult to come back to River, because I have two years on my contract [at Monaco],” he said.
“Options in China, Mexico and Brazil were talked about a bit, but if I were to go back to America, the idea is River, so I didn’t move.”
