Former Premier League defender José Fonte believes Virgil van Dijk will play into his 40s.
Van Dijk, 33, is showing no signs of slowing down as he has spearheaded a Liverpool back line that has allowed a league-best six goals through the first 11 matches of the season.
The Dutch defender continues to show all the physical tools needed to be an elite centre back, and former Southampton man Fonte backs Van Dijk to extend his career for several more years.
"I’d back Virgil van Dijk to play into his 40s because although he still has pace, he would be able to adapt in his positioning and anticipate the game even better as years go on," Fonte told JeffBet.
"If he stays healthy with no injuries he’ll be able to play into his 40s, it’ll just be about what he wants to do with his career because it can be very draining to play at the highest level.
"You have to put in so much work everyday. But physically he is a monster, one of the best specimens I've seen.
"As a centre back he wins all his headers, wins all his duels fast, he’s good on the ball, he's a complete player."
