Atletico Madrid have confirmed that winger Gelson Martins has completed a permanent move to AS Monaco, just one year after joining the club from Sporting CP.
The 24-year-old left the Portuguese club amid a player exodus last summer, but failed to fit into Diego Simeone's system, and was loaned out to Monaco in the second half of last season.
He impressed despite difficult circumstances in France, scoring four times and contributing four assists to help his new side avoid a disastrous relegation, and as per an Atletico statement, he will join on a permanent basis for an as-yet undisclosed fee.
