Chelsea boss Frank Lampard: "It was frustrating for different reasons.
"In the first half, the game was there to be won. We weren't ruthless enough. We got the goal and we had the possession, but we just didn't kill the game off.
"We allowed them to stay in the game. In the end it was a wonder goal but we were lucky not to lose the game.
"In the end, the tactics matched up for both teams but they were better than us. We have to take that on the chin.
"[The lack of consistency] is a concern. It's something we absolutely have to look at.
"We have to look at the game today. It's a point, but I'm not happy with the performance."
Brighton manager Graham Potter: "I thought our play was really brave and we got our reward.
"Everyone is delighted for Jahanbakhsh. He's worked so hard and waited so long, and to have his freshness off the bench was the thinking and he popped up with a great strike.
"He's had to be patient, but he's got qualities and he's getting his reward.
"I'm really proud of the performance. We need to carry that forward and get some more points."
