Enzo Maresca's Chelsea secured their place in the final of the Club World Cup as they defeated Fluminense 2-0 in an impressive display from the Blues.

Two goals from João Pedro on his full debut for the club were enough to ensure that they would progress to the final round.

Fluminense had no response to the Blues, as they struggled to create many clear-cut chances to threaten Robert Sanchez with.

Here are four things we learnt from the match:

  • João Pedro stars in his full Chelsea debut

As far as debuts go, it is hard to imagine more of a better one for João Pedro. The Brazilian, who arrived from Brighton a week ago in a deal worth up to £60m, displayed exactly why his pricetag was so high, with two well-taken goals against his former club.

His first goal was a wonderfully curled effort into the top right corner from the edge of the box that left Fabio in the Fluminense goal with no chance.

The second goal came on the other side of half-time as Chelsea were on the break. The Blues had a four-on-two advantage, but Pedro still opted to take the shot, which he rifled off the bottom of the bar and back into the net.

It could not have gone much better for Pedro, who has certainly given Enzo Maresca some selection headaches ahead of the final and the new Premier League season.

One of the biggest concerns for the Blues ahead of this match was how they were going to fare defensively without the service of Levi Colwill. The young centre-back has developed significantly throughout this season, turning into a key defensive figure for Chelsea.

As expected, Maresca opted to select Tosin to occupy Colwill's position for the clash with Fluminense, with Benoit Badiashile remaining out of contention with an injury.

Colwill's absence was not an issue against Fluminense as Tosin was defensively solid, not allowing their opponents to capitalise on the suspension of the 22-year-old.

He handled all his defensive duties flawlessly alongside Trevoh Chalobah and contributed to build-up play, completing the most accurate passes of anyone on the pitch for either side.

A yellow card in the quarter finals against Al Hilal saw Argentinian defender Juan Freytes ruled out of the match with Chelsea. This was a huge loss for Fluminense as Freytes has arguably been their most consistent defender throughout this tournament and would be much needed against a team like Chelsea.

Malo Gusto and Christopher Nkunku had a lot of joy down the right as Thiago Santos, selected in place of Freytes, struggled to prevent Chelsea attacks.

Freytes may well have given the right-hand side of Chelsea's team more problems in their offensive phases. If he had avoided that yellow card in the previous match, the story of the game may well have been a different one.

Chelsea have progressed significantly since the start of the season.

At the start of the season, it was hard to imagine Chelsea coming this far in less than a year. Both offensiveky and certainly defensively, there is a clear difference in the Blues.

This difference has given them a great chance to lift the Club World Cup trophy on Sunday. This feat would mark just how much the team have improved.

With the new signings that have been brought in this summer, alongside players that Enzo Maresca has developed, such as Levi Colwill and Enzo Fernandez, Chelsea certainly look back on track, if they did not already, following the UEFA Conference League Final.
