Manchester United legend Ryan Giggs expects his record of 800 games to eventually be beaten.
"They probably said the same thing when Sir Bobby Charlton retired after 759 games," said the 35-year-old.
"But I wouldn't be surprised if someone went past my record.
"The way players look after themselves now, if they get into a first team at 18 or 19 and stay relatively injury-free they can do it.
"It is a long time and a lot of games but you have other big players at big clubs who have stayed for a long time.
"They are getting challenged all the time, so there is no need to move on and improve yourself."
