Ben Chilwell’s late goal in Portugal has made this a much easier task for Chelsea, two goals to the good and with the cushion of both those goals coming away from home, meaning Porto will need to score at least twice to avoid being knocked out of the Champions League at the quarter-final stage.

If Thomas Tuchel wanted a reaction from his team after their shock 5-2 defeat to West Brom a couple of weeks ago, then he has certainly received it, Chelsea producing a professional performance in the first leg, before putting Crystal Palace well and truly to the sword at the weekend.

Chelsea beat Roy Hodgson’s men 4-1, an impressive enough victory looking purely at the scoreline, but in reality, the winning margin could have been far higher for the Blues, with Kai Havertz in particular missing a couple of really good opportunities.

The match against Palace showed a distinct move away from the more pragmatic approach adopted since Tuchel’s appointment, with less emphasis on keeping the ball at all costs, and much more on creating goal scoring opportunities.

Have Chelsea changed their style of play?

Jorginho, in particular, was far more positive with his passing, something that has a huge bearing on the way Chelsea play. When the Italy international drops balls in behind the opposition, like he did against Palace, it gives the opposing defence far more to think about.

Defending against possession-based team who slowly move the ball from one side of the pitch is far easier than defending against a team that are comfortable on the ball, but can also turn you around and get you running towards your own goal seemingly at will.
