Jack Grealish revealed he overcame illness to play a starring role in Manchester City's victory over Liverpool.

Pep Guardiola's side maintained the pressure on Premier League leaders Arsenal, reducing the deficit to five points after coming from behind to run out 4-1 winners at the Etihad Stadium.

Grealish assisted Julian Alvarez for the hosts' first goal - cancelling out Mohamed Salah's opener - before getting on the scoresheet himself to seal the victory 16 minutes from time.

The England international's contribution to clinching another important three points was all the more impressive considering he did not feel at his best. 

"We knew it was going to be a tough game playing against Liverpool," he told BT Sport. "The first game after the international break is always difficult, so we wanted to start it right – this last period of the season.

"Liverpool are so dangerous with the players they have up front, so we went 1-0 down. Then you don't fear the worst, but think it's going to be a tough game to get back into. We responded brilliantly and thought we were excellent, especially in the second half.

"We had a chat between ourselves and with the manager [at half-time], and he said we have to stay in the game. I thought we were good [in the] first half apart from the goal. I was in the toilet at half-time, I felt sick all morning but fine now, I feel buzzing."

Grealish continued his resurgence having now been directly involved in eight Premier League goals since the World Cup (scored three, assisted five), and he feels that normal service has been resumed with his side looking to hunt down Arsenal.

"I love it - I love playing, training," he continued. "When it's going well, there's nothing better. I feel back to my normal self, feel fit and back to confidence - scoring and getting the assist.

"Arsenal are a great team, it's in their hands, so we've just got to keep doing what we can to chase them down."
