Crystal Palace are preparing for their second season in under Patrick Vieira and will be looking to build on their 12th place finish from the last campaign.
Ebiowei, 18, will be a decent long-term option for the London club and has linked up with ex-Rams teammate Luke Plange at Selhurst Park after he agreed to join the Premier League outfit back in January.
Johnstone, on the other hand, will provide strong competition with Vicente Guaita for the number one spot next term.
Palace have been linked with a lot of players over recent times and it will be interesting to see who they move for next.
