Manchester City striker Edin Dzeko is delighted to have their title challenge back in their own hands.
Liverpool were shocked at home by Chelsea to hand the advantage back to City.
"That's the English Premier League! Everything can change in just one game," said Dzeko.
"That is what happened, with Chelsea beating Liverpool, knowing that they have a massive game on Wednesday in the Champions League.
"It was also important for us to go to Palace and win the game and we did our job."
