Arsenal have been linked with Brazilian attacker Diego Costa.
Reports over the weekend linked Arsenal with signing another of Atletico Madrid's forwards; Diego Costa.
But apart from being a strike-partner to Radamel Falcao, who is he?
Here are five facts about him...
1) Costa is 24-years-old and is really enjoying a breakthrough season at Atletico, having been on loan at Rayo Vallecano last campaign, scoring 16 goals.
2) To date this season Costa has scored 15 times, six in La Liga, three in the Europa League and seven in the Copa del Rey, and provided 13 assists.
3) His agent is Jorge Mendes, who represents Cristiano Ronaldo, Falcao, Jose Mourinho, and Manchester United target Ezequiel Garay.
4) Costa's form saw him win his first ever international cap last week, in Brazil's 2-2 draw with Italy.
5) While able to play as a left-winger, Costa's success this season has come as a centre-forward. He can also drop deep and play as an attacking midfielder, as he has done on two occasions for Atletico in 2012/13.
