Hiddink has lost only once in 22 games in charge of Chelsea
Chelsea's departing manager Guus Hiddink says winning the FA Cup is one of the greatest achievements in his decorated managerial career.
The Blues capped the Dutchman's four-month spell as boss with a 2-1 victory over Everton in the 128th Cup final at Wembley on Saturday.
"It was one of the biggest achievements of my career, winning in the Mecca of world football," said Hiddink.
"The FA Cup is something you truly cannot believe."
Blues interim boss Hiddink - who enjoyed European Cup-winning success with PSV Eindhoven, as well as
impressive World Cup campaigns with Australia
and South Korea - will resume his role as Russia coach on a full-time basis in June and was granted a farewell to remember thanks to Frank Lampard's second-half winner.
Earlier, Didier Drogba had headed Chelsea level after Everton's Louis Saha scored the quickest goal in an FA Cup final after just 25 seconds.
The Cup victory marks a fitting end to an impressive run of only a single defeat in 22 matches the Dutchman has been in charge of that resulted in the club finish third in the Premier League and narrowly miss out on a place in the Champions League final.
"We had some wonderful performances in the Premier League and also in the Champions League and this is the highlight, to win the FA Cup," said Hiddink.
"I loved it so much, I enjoyed working with big stars but they knew what it's all about. They showed in the Premier League and Champions League and here, a lot of character.
"We have worked so hard since February and I respect these guys very much."
Captain John Terry paid tribute to the impact Hiddink has made - not just in the final but during the whole 104 days of his tenure - and revealed the players had clubbed together to buy him a thank-you gift.
"Credit to him. At half-time he kept things calm. There were no rash changes," Terry said.
"Two years without a trophy, it's been too long. We've seen Man Utd and others winning trophies and it's good to get it (the winning feeling) back.
"We gave him (Hiddink) an engraved watch and a shirt signed by all the lads. He was really touched."
Match-winner Lampard echoed Terry's sentiments, saying: "He's a great manager and a great man.
"It's a great send-off for him and we're delighted to give him a trophy."
