Nikola Tavares and David Boateng have both signed new contracts with Crystal Palace.
The pair join fellow Development talents James Daly and Sean Robertson as players to have recently signed new contracts with the club.
Speaking after putting pen to paper, Boateng, 18, said: "I'm very, very happy to have signed with Palace. They're one of the best teams in London and I believe that I can push on and maybe play for them in the future. I guarantee that if I do play for them, I will put in everything.
"I feel very good. It shows that they believe in me, shows that they know what I'm capable of and that I can push on. I'm very, very proud."
Tavares also expressed his pride in signing a new contract, having made the first team squad last season. He told cpfc.co.uk: I'm really excited actually. It's a big year for me, I think I'm getting to that age now where I need to be knocking on the first team manager's door and trying to prove myself.
It was a great way to finish off last season, being on the bench against Bournemouth. It was a great way to finish the season, almost like a little reward for me and that's spurred me on to go again this season and show what I'm about."
Crystal Palace have also announced the signing of Development player Lewis Hobbs on a one-year contract.
