It is half-time and they are currently losing 2-1 to Spurs, but i think Chelsea are title contenders this season, if you are going to put Arsenal up there as title contenders, then i am afraid you have to add Chelsea, because they have been as good as Arsenal, prolly even better.
The question around Chelsea being contenders is more about their performance in recent years than this season. Arsenal have been runners up 2 years in a row, Liverpool have been up there for the past 6 or 7 seasons and Man City are well, Man City, before the season starts, these are the title contenders.
Chelsea are trying to break into that conversation and have to do much more than the rest.
That being said, we might not have "title contenders" this season, it is looking like we are gonna have a runaway champion in Liverpool, whilst other top teams battle for top 4.
It's turning out to be a dream weekend for Liverpool. Without playing they expected their lead to be cut by much, but they are looking to stay at least 5 points clear of everyone.
Potential runaway champions.
