The Brazillian born Spanish international struggled against English opposition, as Atletico Madrid faced Chelsea in the Champions League semi finals.
Tuesday night's game between Atletico Madrid and Chelsea marked the first competitive game Diego Costa has ever played against an English team.
Given that a possible transfer to Jose Mourinho's side is expected this summer, the forward would have been eager to put on an impressive performance, to either encourage a bid or make it clear his heart was still with Atletico.
In contrast to Los Colchoneros' current golden boy was former favourite Fernando Torres, Chelsea's own centre forward and rumoured to be a target for a return to the Estadio Vicente Calderon.
Unlike Costa, who has a phenomenal record of 35 goals in 46 games this year, Torres has struggled for any semblance of form all season, yet to hit double figures with just 9 goals in 35 matches.
He isn't the only Chelsea striker to struggle, Demba Ba, who came on as a late sub in the game, has 7 in 26, while summer signing Samuel Etoo has a slightly better 14 in 34 despite being in his mid 30s.
Costa's possible arrival would be for a huge fee, but how did he compare to Torres in the semi final first leg tie between the two sides?
To be honest, it was likely one of Costa's most disappointing displays of the season. Chelsea sat back and crowded the penalty box giving the former Valladolid man no time or space to influence the game. Against the likes of John Terry and Gary Cahill, who defended superbly, plus a David Luiz who often slotted back into defence, Costa struggled to threaten and his only attempts on goal were a series of headers and an effort blocked by Cesar Azpilicueta.
The forward and Terry were in each other's faces all night, squaring up at one point, meaning that a possible move for the Atletico man may be awkward with his future captain at first.
Torres worked hard at the other end to make an impact but was often very much lacking in support from his teammates. The Spaniard made a couple of good runs, one which ended with a comfortable save from Thibaut Courtois, and the other drawing a foul late on just metres from the box. But for most of the game he merely wasn't given the ball, and once he had it there was too much for him to do.
It's feasible that Costa would be an improvement on Torres and co in such circumstances, and given his form in La Liga he should have the confidence to net in the Premier League too, but he didn't convince against his possible future employers in the first half of the tie. It will be interesting to see how he does at Stamford Bridge next week, when there should be a lot more space for him to exploit.
