Marcos “Rony” Lopes looks set to depart the Etihad, having spent last season on loan in France with Lille.
Manchester Evening News are reporting that the 19-year-old is closing in on a move to the principality club, having failed to force his way into Manuel Pellegrini’s first team plans.
A former Benfica academy star, the attacking midfielder spent last season on loan in France with Lille and was largely impressive.
In 23 Ligue 1 appearances for LOSC, the midfielder scored three goals and shone in a team that also featured Liverpool striker Divock Origi.
But that form was evidently not enough to catch the eye of Pellegrini, with Monaco now set to swoop in with a substantial offer for the young star.
Lopes has been capped by Portugal at six different levels of youth football and was part of the Under-20 team that advanced to the quarter-finals of the 2015 Under-20 World Cup.
Regarded as one for the future of the Sky Blues, his exit would represent a blow to the club’s long-term plans, if confirmed.
