Arsenal are following Gelson Martins ahead of a bid this summer, but Sporting CP will only sell for close to the player’s release clause, according to reports in Portugal.

Saturday’s O Jogo writes that Sporting president Bruno de Carvalho has made it clear to any agents who request information about the player that they will only negotiate with teams who offer “values very close to the termination clauses”. In Gelson’s case, that’s €60m (£53m).

The Portuguese outlet writes that Arsenal are following the 23-year-old, along with Borussia Dortmund, Bayern Munich, Chelsea and Tottenham. The players contract lasts until 2022, so there’s no way around negotiating with the club.

Martins has had a positive season in Portugal scoring 13 goals and providing 12 assists from the wing. He is a strong dribbler, who holds onto the ball well and creates chances for his teammates.

He’s also having a particularly strong end to the season, as he was named WhoScored‘s man-of-the-match in Sporting’s last game against Benfica, who are second place in the Primeira Liga table. Arguably at this stage he’s got as much motivation as anyone to perform. He’s playing for a place in Portugal’s World Cup squad this summer.

It’s very possible the player will catch the eye even more in Russia next month. If Arsenal really are after him, they should aim to get a deal done before then.
