Spanish International Striker Diego Costa, the reason The Blue are on top of their game

If Chelsea go on to win the Premier League title this season, Diego Costa's goals will be a big reason the Blues top the table.

The Spain international scored two more goals on Tuesday, leading the Blues to a crucial 4-2 victory over Southampton at Stamford Bridge.
Chelsea's win at least temporarily extended their lead to seven points over second-placed Tottenham. That cushion can be significantly attributed to Costa, who has managed to earn a league-best 15 points from his 19 Premier League goals.
Costa is tied with Alexis Sanchez for the third-most goals in the league this season. Harry Kane (20) and Romelu Lukaku (24) occupy the top two places in the race for the Golden Boot.
