With Stewart Downing also expected to leave during the transfer window, new boss Alex McLeish may have to shell out big money to replace the dynamic duo.
But Mortimer believes the Scot has a tailor-made replacement in the form of Albrighton, who has been on England Under 21 duty this summer.
“Now Ashley Young has gone to Manchester United, as expected, Villa will need someone who can take his position in the team,” said Mortimer.
“But they don’t have to sign somebody for big money – maybe they can look within the ranks at who they have already got.
“I like Marc Albrighton is an exciting talent, although he can still improve aspects of his game and needs someone from the coaching staff to work with him on certain things. If Villa do that he can fill Ashley Young’s shoes.
“There are a few young players who are worth giving a chance to, rather than going out and spending money on people who might not move to Villa for the right reasons.
“There are many players who don’t move for the right reasons and do it just for the money.”
