Because of having 7 players on the bench Warnock is likely to have a keeper as one of them.
Darryl Flahavan is still looking to leave rather than be understudy to Julian Speroni. Warnock though would look to get a replacement in before Darryl moves on.
"Obviously with the number of substitutes we can name next season there is more scope for me to name a sub keeper and that's a big possibility for us," Warnock told the Croydon Advertiser.
"We would need to have a keeper lined up before we let Darryl leave - mainly because we do not have enough players to fill the other two slots."
