Chelsea play at home and they don't have the extra pressure of other championships... Spurs have a Europa League game coming up against a serious opponent... Chelsea are more motivated to take three points and stay in the UCL zone... Spurs have no chance to get into the European zone this season... I think Chelsea will win today...
I don't trust Tottenham as much as I trust Chelsea when comparing both team's consistency this season. So in this encounter I see Chelsea winning this game on top of a home advantage they also have. Chelsea is fighting for a spot in the top four and that's enough motivation to give their all to make sure they win to get all 3 points to continue to stay above Manchester city. I think their distractions in their various European competitions wouldn't be an excuse in whatever results that happens to be tonight.
If you want to compare both teams you will need to make use of their stats this season. When you campare stats for both teams, it is clear that Chelsea have a better record this season than Tottenham. Chelsea also have a chance to finish in top four over Tottenham meaning there is a possibility of playing Champions League football next season for Chelsea although both sides are still in European competitions and have hopes of winning.
