I did expect Chelsea to win the game because Tottenham on their own have not been very good they are inconsistent, Chelsea is having a better season than they are doing right now, Tottenham have not had so grate luck with injuries and they do not have a very good attack, the midfield is not so good at all, They have some new players who are trying to get used to the playing system are they do have some young players who needs time to get used to the league and dont possesses so much experience,
The game is a more important game for Chelsea who are fighting for Top 4 place and Tottenham are actually fighting for nothing right now, i believe there season is over and they should focus on the European League
It looks like you missed something because the game ended a few hours before you wrote this post and Chelsea have already taken 3 points in a game that was quite heated in terms of tension and pace.
Actually if I can conclude in this game it looks that the only thing that is hotter is the style of play where there are a lot of fouls and cards that occur in this match but when it comes to actual opportunities I don't see anything that can really be said to be extraordinary because indeed both clubs look a little cautious in carrying out attacking schemes that make it not too optimal.
Fortunately in this case Tottenham did not have a good enough finisher so Chelsea got more with 1 goal from Enzo because if this did not happen then they could have lost 3 points.
This game was interesting to watch especially for Chelsea because they recorded a win at home which was critical to their top four spots this game was a fair one and the better side got the three points because they deserve the victory because Tottenham was not playing like a team that was serious about changing their fortune in the league table, maresca has really improved this Chelsea side because this time last season they where no where close to top four spots
