Falcao scored just five goals in two years on loan but is now getting back to his best, claimed Vasilyev.
He told the Daily Mail: “Both clubs in England failed to relaunch him.
“He is the same Falcao as ever. We've seen that in pre-season.
“He scores goals, he's there and he is motivated, we are motivated and I think this will be his year.
“You have to be patient but the big clubs have other topics on their agenda.
“If you sign a player of this magnitude after a big injury it takes time and games to get him back into shape.
“We see all the qualities are there and it is a matter of time. Monaco will make every effort and you will see a very different Falcao this season to the one you saw in England."
