He joined from Athletic Bilbao for £30million in 2014, signing a four-year-deal, with an option for a further 12 months, said to be worth £100,000-a-week.
Man United are hoping a new deal will keep him at Old Trafford, especially as the Spaniard has attracted interest from Barcelona and Atletico Madrid this summer.
United’s hierarchy are allegedly ready to hand him a new deal worth around £150,000-a-week that will keep him at Old Trafford until 2021.
He was voted United’s Player of the Year last season and has been a completely new player under Mourinho, earning his first cap for the Spanish national side.
Herrera has formed a solid partnership with Paul Pogba and although Mourinho was previously unsure about his midfield partnership, it’s now clear the 27-year-old has a vital role to play, as a player who is now seen as a potential captain at the club.
