Nottingham Forest have signed winger Gil Bastiao Dias on a season-long loan from French Ligue One side Monaco.

The deal gives the Championship club an option to make the transfer permanent at the end of next season.

The 21-year-old spent the 2017-18 campaign on loan with Italian Serie A side Fiorentina.

Dias is the third Portugal Under-21 international to join Forest so far this summer following midfielder Joao Carvalho and winger Diogo Goncalves.

Carvalho cost a club-record £13.2m fee, while Goncalves has also been signed on loan.
