Who's even talking about Chelsea winning the English Premier League title this season? Unless the person's knowledge about the performance of the top four teams in the league table is very limited. Chelsea can only fight for a place in the top four of the league which we all know is very competitive at the moment but though it's still mathematically possible for them to win the league this season, but I think will be impossible for such thing to happen at the end of the season.
What must be understood at this time is that Liverpool is already difficult to catch up with by all teams in the Premier League, let alone Chelsea who are currently in the top four of the standings, Arsenal alone who are still in second place in the standings find it very difficult to reduce the points gap with Liverpool who currently have a gap of 12 points with Arsenal. Moreover, for Chelsea whose distance is getting further away so that it can be considered less possible for Chelsea to shift several teams including Liverpool who are currently at the top of the standings.
