Ian Maatsen is joining Aston Villa for a reported ₤37.5m fee which is a good piece of business for Chelsea at the moment but could come back to haunt them eventually.
When asked if Chelsea were going to regret the deal, ex-Aston Villa forward Gabby Agbonlahor said: "100%.
"I get why they are letting him go, £35-40million, they've already got Marc Cucurella, they've got Ben Chilwell, they don't need another left back.
"But he could end up being better than both. Young age of 22, we'll bite their hands off.
"He's a player who's going to play every week, six-year deal, Aston Villa are going to start doing that as well with youngsters, getting them signed up long term.
"So I think it's one that Chelsea will regret and one that Aston Villa fans are going to love. He'll start and then it wouldn't surprise me if Lucas Digne moves on and Alex Moreno is the back-up left back. So exciting times at Aston Villa."
