Liverpool are currently top of the table with four games remaining in the season, and Zidane believes that Gerrard's loyalty to the club means that success this season would be deserved.
"He has had a great career winning many things - but it would be a big shame for him if he was never to win the league with Liverpool," the former Real Madrid midfielder is quoted as saying by the Daily Mail.
"For everything that he has given - he deserves a league title. He could have played for any team in Europe, but he turned them down. That sort of loyalty should be rewarded with a title."
Liverpool take on Norwich City at Carrow Road on Sunday.
