Luke Young says Marc Albrighton's return is a big boost for Aston Villa.
The England U21 made his comeback in Monday's 3-0 defeat to Liverpool after being sidelined for a fortnight with appendicitis.
"I think at the minute it's Marc's raw pace and the fact that nobody knows about him - although they're finding out now," said full-back Young to Villa's website.
"Obviously in training I know what's coming, so it's a little bit easier for me to realise what he's going to do.
"But when these players are coming up against him at the minute they're not quite sure what he's about, so he's surprising a few at Premier League level.
"He's made a few look a little bit inexperienced when they are experienced players.
"He gave Evra a tough time and Herita Ilunga at West Ham. These are experienced pros and he's given them really tough games."
