It was a frustrating night for Chelsea at the Amex Stadium, as the Blues were held to a 1-1 draw.
Chelsea had taken the lead in the first half courtesy of a long range strike from Hakim Ziyech, but Adam Webster’s second-half header cancelled out Chelsea’s lead.
It was the same story at Stamford Bridge in the reverse fixture, as a late Danny Welbeck header prevented Chelsea from grabbing all three points.
Speaking after the game, Chelsea goalkeeper admitted that the team wasn’t happy with what happened at Amex and also hailed the Seagulls for their efforts in both legs.
Kepa said: “We are not happy of course, we dropped two points and we didn’t play well.
“In both games, at home and here, we scored first and were in a good position to control the game, but they played a very physical game, one against one in all the pitch.
“It’s not easy to control the game against Brighton. You have space behind the line, you have a chance to go one against one, but in the same way they have those chances.
“It was a very open game. We had to create more chances. We had opportunities near the box to go one against one, to shoot, and maybe that’s something we have to improve.”
Kepa has been in goal for the Blues as Edouard Mendy had since teamed up with Senegal at the Africa Cup of Nations.
The Spaniard produced a superb save to deny Alexis Mac Allister from scoring, but couldn’t do much to prevent Webster from equalising shortly after.
The Chelsea goalkeeper revealed his disappointment at conceding that goal.
“Of course there is disappointment and frustration,” the Spaniard added. “We only got a point because they scored from a set-piece.
“We worked a lot, we ran a lot, but in small details we lost two points. Set-pieces are about concentration, about focus and taking your man.
“We have to look at ourselves, not outside, and improve. There is not one solution. We are working on it, trying to find solutions.”
