Brighton boss Roberto de Zerbi is delighted with Solly March's new deal.
The winger penned terms on Friday.
De Zerbi said: "It's great news, he deserves this new contract. We are happy for him. I am happy for him because he is my player and I want the great players to stay with me. Lallana, Mac Allister, Caicedo and March, they are very big players and I am really pleased for them and for me.
"I have given him the confidence, maybe another way to play, another possibility to score more goals, but the praise is not something that I deserve. Solly was and is a great player and I knew that before I started to work here.
"Solly defends more than [Kaoru] Mitoma. Can he reach 20 goal involvements in a season? Maybe not 20, but 14-15 he is able to achieve. I think he can improve in ball possession and I would like him to stay more inside of the game, but I'm delighted for him and his performances."
