Chelsea 2-0 Brighton: Three reasons why the Blues beat Graham Potter's side | Premier League 2019-20 

A couple of goals from Jorginho and Willian after the break guided Chelsea to their first home league win under Frank Lampard. The victory against Brighton and Hove Albion also sealed a first clean sheet for the Blues, who have already conceded 13 goals thus far.

They began the game at a frenetic pace but couldn't quite break the deadlock despite a slew of chances going their way. Marcos Alonso, Pedro, Tammy Abraham and Ross Barkley all came close to opening the scoring but the hosts headed into the break as the more concerned side.

The above players should really have put the result to bed within the opening 45 minutes, especially because Chelsea have struggled to translate moments into three points so far in all competitions.

However, a solid second half display that saw a couple of goals from their end, aided the Blues to a much-needed victory that, for the time being, takes them to sixth spot on the Premier League ladder.

It was indeed, an all-round performance from Frank Lampard's men, but there were a few substantial reasons that led to the comprehensive win. On that note, let's breakdown the major factors behind Chelsea's win over Brighton.

#3 Lampard's substitutions

Lampard was spot on with his substitutions

Frank Lampard's decision to go with Barkley, who had just played 90 minutes against Grimsby Town in midweek, didn't go too well with the faithful. Further, he started both Willian and Pedro ahead of Christian Pulisic.

However, now with the difficult away fixture at LOSC Lille in sight, Lampard probably made the right move in not starting a few of his preferred first-team stars.

And his substitutions this afternoon were simply bang on. For starters, he muscled Callum Hudson-Odoi in for the hard working Pedro just after the hour mark. The youngster rounded off his first PL appearance since April with an assist, but there was a lot more to his performance.

Hudson-Odoi looked sharp, ready and decisive with his touch and dribbling. The way he tactically carved open spaces to pick out Willian down the far side was spectacular.

Mateo Kovacic injected smoothness in passing and a sense of fluency at the expense of Barkley, who should not only have scored, but also picked passes earlier.

#2 Magnificent performances at the heart of defense

Fikayo Tomori is growing into his Chelsea shirt, week by week

After a long, long wait, Chelsea registered a clean sheet. For sure, Lampard hasn't been helped by the recurring injury setbacks to the likes of Antonio Rudiger but Fikayo Tomori has slotted in imperiously.

The latter has been arguably Chelsea's best defender, much to the surprise of many. We thought it'll take a couple of years for Tomori to develop into a complete center-back, more so because he was behind Rudiger, Andreas Christensen and Kurt Zouma in the pecking order.

But he has come into the side and put in consistent shifts time and time again. Tomori is quick across the ground but always alert to the ball played in. He's safe with and without the ball, as seen in recent performances.

Christensen was superb as well, chipping in with vital blocks and playing a direct role in keeping a clean sheet. A couple of interventions and tackles made by him proved to be massive for the Blues.

Chelsea are slowly beginning to organize themselves better and those are good signs for Lampard.

#1 Energetic build-up and willingness to score

Jorginho once again, was simply marvelous for Chelsea in midfield

From the very beginning of the game, Chelsea began on the front foot. They tested Matt Ryan constantly, finishing the 90 minutes with a staggering 24 attempts on goal with 10 of those being on target.

All in all, the hosts completed a total of 567 passes with 52% possession. And, Lampard's side displayed exciting moments in possession, more often than not.

The likes of Jorginho enjoyed the space ahead of him, which was well-worked by his own positioning and the tactic to deploy Mount and Barkley further forward as a four-man attacking midfield.

Jorginho simply ran the game, supplied passes to all corners, won the ball before anyone else and provided an all-round performance.

Chelsea simply didn't release their foot off the pedal, and that's what perhaps, led to the win. Chances went begging in the first half and much like we've seen so far from the Blues already, this could have gone either way.

But, they stuck to their strengths, maintained a strong foothold in the game and played out at the back with order and discipline.

The fact that they continuously knocked at a shaky Brighton defence led to the error from Adam Webster and then the second goal as well, a move that caught a host of away shirts napping.
