Aldridge was impressed by Reina for their 0-0 draw with Reading.
"For long periods Reina had nothing to do but his concentration was excellent.
"When Reina was called into action early in the second half he pulled off two really good saves.
"Recent results have been frustrating but the real positive has been the clean sheets.
"That's 13 in the league this season now and only Man City have kept more."
