The Atletico Madrid hitman is reportedly on the Gunners' transfer wishlist of strikers and is the preferred choice out of five forwards by our readers
The five-man shortlist comprises Atletico Madrid's Diego Costa, Borussia Dortmund's Robert Lewandoskiw, PSG's Ezequiel Lavezzi, Juventus' Fernando Llorente and AC Milan's Stephan El Shaarawy.
Any of these five will surely be a quality addition and boost the Gunners' chances of landing the league title, with Olivier Giroud their only striker at the moment, although their midfield has the ability to chip in with goals.
And it seems that Costa, who is currently tearing it up in the La Liga, is the preferred choice of Goal Singapore readers for Arsene Wenger to sign.
The 25-year-old garnered 43.2% of the votes when polled, making him the outright favorite ahead of Poland star Lewandowski, who got 32.6%.
Costa is currently the top scorer in Spain with 19 goals, putting him ahead of the likes of Cristiano Ronaldo and Lionel Messi. His two goals in Atletico's 3-2 win over Levante earlier this morning, including a game-winning penalty, fired the Rojiblancos to the top of the table.
The Brazil-born forward has stepped up to the plate and taken over the mantle as the spearhead at the Vicente Calderon following the departure of former star Radamel Falcao in the pre-season, and will no doubt be a major coup if Arsenal can pull it off.
El Shaarawy came in a distant third with 11.4%, while Llorente and Lavezzi had 8.3% and 4.5% respectively.
