The veteran broadcaster had fronted the international music competition since 1973, but handed the reigns over to Norton ahead of this year's event.
Speaking to the Radio Times, he said: "I thought Graham Norton was excellent. People have said his approach was rather like mine, and all I can say is I take that as a compliment."
The 70-year-old went on to say: "I thought [this year] was wonderful. A spectacular show without a flaw in it.... Contrary to what is often believed I love Eurovision, or I couldn't have presented it for as long as I did."
Wogan had previously criticised tactical voting from neighbouring Eastern European countries and branded last year's British result "tremendously disappointing" after Andy Abrahams finished in last place.
