Chelsea controversially held by Swansea

Chelsea will feel as though they dropped two points given their domination, but could have lost the game if it weren't for some late magic from Diego Costa.

The Blues took the lead in the 18th minute when the ball fell to Diego Costa in the penalty area, who placed the ball past Lukas Fabianski in the Swansea goal.

Chelsea should have really made it 2-0 just before the break when the ball fell to Costa once again in the six-yard box, but the striker somehow managed to miss the target from such close range.

After the break, Conte's side continued to dominate, but failed to turn possession and chances into goals. 

Chelsea were then made to pay for their inability to finish when Sigurdsson scored from the spot after he was brought down by Thibault Courtois in the penalty area.

Swansea then completed a dramatic turnaround when Leroy Fer nicked the ball from Gary Cahill and went on to poke the ball past Courtois to put the Swans 2-1 up. However, replays showed that referee Andre Marriner should have probably awarded Chelsea a free-kick for Fer's challenge on the Chelsea defender.

It seemed as though Chelsea may have been heading for an unlikely defeat, but they were thankful to Costa once again, who equalised with an impressive close range bicycle kick.

The former Atletico Madrid striker then could have had a hat-trick just minutes later, but Fabianski was equal to the Chelsea man's effort, meaning the spoils were shared at the Liberty Stadium.
