They do not necessarily have to lose 3 straight matches, there are 26 matches left. Dropping points at any point in the season would put pressure on then and reduce the gap. And I believe Liverpool would lose this season, but so will their opponents. If they (Liverpool) can be more consistent then they will be champions at the end of the season.
It would be quite remarkable if they top the league from the beginning to the end
@Upgrade00 as a Manchester United fan Im hating the fact that Liverpool are so close to winning the title, and theres no team in the Premier League that can beat them. I know many of youll will argue that their winning streak will end soon, but I dont think so itll end anytime soon because Liverpool are the new invincibles like Arsenal once was.
