Rob Holding has signed a new three-year contract at Arsenal with the option for a further year following an impressive 12 months.
The centre-back has become a regular under Mikel Arteta this season and played 18 times in all competitions - the same total he managed throughout the whole of the 2019-20 campaign.
Technical director Edu told the club's official website: 'He is 25-years-old so is still coming into the peak of his career and we are delighted that he'll be with us during these important years.'
Arteta added: 'Since I started as manager, I have been hugely impressed with Rob's contribution to the club and the dressing room, on and off the pitch.
'We are all very happy that Rob has signed a new contract, he is very popular with all the players and staff and we're looking forward to watching him continue to grow with us in the coming years.'
