Merson, who works as a television pundit, believes Pogba, the world’s most expensive footballer, is not currently living up to the world-record £89m transfer fee.
Henderson, meanwhile, captains a Liverpool side that has started the season impressively and took the England armband for the first time in Tuesday’s 0-0 World Cup qualifying draw with Slovenia.
When asked which midfielder he would prefer to have in his side going into Monday’s game, Merson told Sky Sports: “Today, Jordan Henderson.
“Over the next 10 years, I don't know – it probably should be Pogba considering how much money they spent.
“Henderson has been as good as anybody in the Premier League. Credit where credit is due, he's been outstanding. Pogba has been struggling.”
Pogba swapped Juventus for United, the club which handed him his professional debut, following a protracted transfer saga in the summer.
The France international has scored once in eight club appearances since his return to Old Trafford and notched in his national side’s 1-0 victory over the Netherlands on Monday.Reuse content
