Maarten Stekelenburg has vowed to push Everton team-mate Jordan Pickford into maintaining his standards after signing a new contract.
Pickford, 24, played every Premier League match for the Toffees last term and went on to star in England's run to the World Cup semi-finals.
The goalkeeper's form consigned the experienced Stekelenburg to the role of back-up in his second season at Goodison Park.
But the 35-year-old Netherlands international, who was handed a new two-year deal on Monday, has resolved to do everything possible to keep the number one on his toes.
"Jordan had a very good 2017-18 season and played superbly as well for England at the World Cup," Stekelenburg told his club's website.
