Crystal Palace boss Roy Hodgson says he'll keep trying to bring through Matheus Franca and David Ozoh.
The pair saw more minutes in the FA Cup replay defeat to Everton.
Hodgson said, They're young, aren't they? I mean they're young, they have ambitions, a lot of aspirations as well, and especially if you've come from Brazil like Frana, you've come here with dreams and thoughts of taking the Premier League by storm.
It's not that easy, unfortunately, for players coming in when they're young and of course he came in with an injury into the bargain which took six or seven weeks for us to sort out. Ozoh has come in from our own academy.
I think these players have to come to terms with the fact that it's not going to be easy to break into a Premier League side. We have some good players and especially when we get everybody back from the injury and from the AFCON tournament, we have quite a strong, experienced and steady side.
But it was good that they got at least that 30 minutes the other night and it enabled me, of course, also to spare one or two players."
