Jose Mourinho's team leads the Premier League after winning each of their five league games so far.

Chelsea fans have reason to believe. The Blues lead Premier League standings after a come-from-behind win against Swansea City, taking advantage of a hat-trick scored by their world-class striker Diego Costa.

But things did not start quite as Jose Mourinho and his fans expected, when John Terry struck the ball inside his own penalty box giving the visitors an early lead. Chelsea struggled throughout the first half to equalize, having their efforts rewarded with Diego Costa's first goal of the day just before the halftime whistle.

After the break, things turned around for Roman Abramovich's team. Just after ten minutes, Diego Costa struck the ball inside Lukas Fabianski's goal, giving Chelsea the needed boost to carry on. Eleven minutes later, Costa scored his first hat-trick as a Blue. The Spanish player was substituted by Loic Remy, who managed to score his first goal playing for Chelsea nine minutes after getting on the pitch. Five minutes before the game ended, Swansea City scored via Jonathan Shelvey, giving them some dignity after losing the lead.

Blues' fans had a field day talking about this match, and some of them believe this Premier League will end up being theirs. Enjoy their reactions!
