Heading into the Premier League's final day, City require just one point at home to West Ham to win the title, while Brendan Rodgers's side must beat Newcastle at Anfield and hope their rivals slip up.

"My team-mates were helping me, but I couldn't stop. I play every single game from the heart and I was very sad," Suarez told the Daily Mirror.
"I was sad for my team-mates, who have done so much. I was sad that I had missed chances.
"It is difficult. At the start of the season, our aim was to finish in the top four and qualify for the Champions League, so it has been good.
"But then we got into a position when we thought we could win the league, but lost against Chelsea and then that happened at Crystal Palace."
Reflecting on a season that has so far seen him produce 31 goals and 12 assists - leading the league in both categories - the 27-year-old said he could not recall a better campaign personally.
"It is amazing. I can say that this has been the best season of my career," the Uruguayan said.
"It is great that we have achieved Champions League football and I have taken a lot of praise for being top scorer. So, it's been a nice season for me but, most importantly, I recognise much more the work of my team-mates.
"They have done a great job. If we all stay together, we can stay at this level. We have good players and a really good manager."
A goal on Sunday against Newcastle will see Suarez become the first player to score more than 31 times in a 38-game Premier League season.
