His goalscoring exploits in West London since moving from La Liga champions Atletico Madrid have seen Costa regarded as one of the signings of the summer, and he is leading Chelsea's charge for the Premier League title. Having fully recovered from an injury that kept him out of action since the last international break, the 26-year-old will not feature for Spain in the upcoming round of international fixtures, allowing him to prepare for the return of the Premier League and Champions League in two weeks.
However, whilst his remarkable goalscoring feats have been lavished with praise, the forward’s work ethic and pressing ability have often been overlooked, despite being key parts of his game. He appears to be moulding perfectly to Jose Mourinho’s style of play, and, in the tie with Liverpool, the forward was pressing the Reds’ defenders up until his 90th minute substitution.
Having endured a number of years without a top quality striker at Stamford Bridge, the cub finally appear to have found the missing piece of their puzzle, and Costa’s international teammate Cesar Azpilicueta believes that the forward’s passion to fight for the team is ‘great’ for everyone involved with Chelsea.
Speaking to the Standard, the 25-year-old full-back said: "We're lucky to have three really good strikers. We showed it when he was out, when Didier [Drogba] and Loic [Remy] came in and were scoring.
"Now he’s [Costa] back and scoring. He plays with high passion, he's always fighting for team, and is even after goals in training - he's a great finisher.
"If we analyse him he scores but helps so much in the team. Even in last five or 10 minutes he was pressing high and doing his job. That's great for the whole team.”
Costa has been too good for nearly every team that has faced him this season, only failing to score in the Premier League against Manchester City and QPR - a game in which he was still recovering from injury. Whilst Blues fans will be hoping to see his remarkable run of goalscoring form continue, his contribution to the defensive phase of the game makes him a valuable part of Jose Mourinho’s first-team set-up - regardless of his form in the final third of the pitch.
