After captaining England to their first major tournament final since 1966 this summer, Kane has quickly put aside any distractions and got back to work for his country.
The Tottenham striker failed to complete a £150million move to Manchester City, and has since returned to the fold with Spurs and England after an extended holiday.
Kane has added two more goals to his international tally during the current break, scoring the second goal in both of England's 4-0 World Cup qualifying wins over Hungary and Andorra.
The 28-year-old now sits on 40 goals for his country, and is gradually approaching Rooney's record of 53.
Derby manager Rooney sees Kane taking his crown as a formality, and told talkSPORT: "I'm fully expecting Harry Kane to get that record, he's a fantastic player and goalscorer.
"Obviously he's got time on his side, and I'd be the first to congratulate him."
Rooney took the overall scoring record from Bobby Charlton in 2015, netting his 50th England goal against Switzerland in a Euro 2016 qualifier.
He then managed three more goals against France, Australia and Iceland before retiring, extending his benchmark at the top of the charts.
Kane, though, has been creating his own legacy, taking his major tournament total for England to a record-equalling 10 goals with four at Euro 2020 this summer.
That record has seen him exceed any of Rooney's achievements with the national team, making a semi-final at the World Cup in 2018 and a final this year, whereas Rooney only managed four quarter-final appearances.
And Rooney believes that when, not if, Kane beats his record, he will have earned all the plaudits coming his way
"Records are great of course but they're there to be broken," Rooney said. "When Harry does break that record he deserves all the praise and credit that he gets because it's a great honour to hold that record."
