French side Monaco have extended the loan of Brazilian central defender Wallace by a further season from his parent club Sporting Braga, it was announced on Friday.

The 20-year-old has signed on again after making 22 appearances (four in the Champions League) for the Ligue 1 outfit while on loan in the 2014/15 campaign.

Wallace, who has represented Brazil at under-20 and under-21 level, hopes to play at the 2016 Rio Olympics.

The defender began training with Monaco, who finished third in France last season, at the start of this week ahead of the club's mini tour of Lubin, Poland.

Monaco have selected a 25-man squad for the friendly tournament in Poland where they'll take on German Bundesliga side Hannover, Ukrainian heavyweights Shakhtar Donetsk and hosts Slask Wroclaw.
