"To be the first club to have won everything possible, you can see the fans celebrating now and it shows how much it means to them," he told TNT Sports.

"We just had to wait and pick our moments, and that is what we did in the second half.
"We have achieved everything we wanted to do. It feels amazing to win my first European competition with Chelsea; hopefully, there are many more to come.
"And getting Champions League for next season, I don't think you can end any better than that."
22:21 BST - Chelsea finally get their hands on the trophy!
22:14 BST - Chelsea captain Reece James was disappointed not to start but glad to get over the line in tonight's Conference League final.

"It's devastating to know you're not starting, but it's the manager's decision, and I was ready to come on when needed.
"We needed a reaction in the second half and we got it. The Conference League was something we had to win. Next season we go again in the Champions League."

18:32 BST - Real Betis coach Manuel Pellegrini said Brazil winger Antony wanted "revenge" when he arrived in Spain after flopping at Manchester United as their team prepared for Wednesday's UEFA Conference League final against Chelsea.
Antony joined the Liga side on loan in January and has roared back to form, scoring nine times and providing five assists in 25 games.
"I spoke with him before he came to Betis," Pellegrini said.
"He told me that he was not playing because he was not happy.
"Also, he wanted revenge. Here in Betis, I think that he did it in the way we know that he can."

18:20 BST - Standing between Chelsea and the Conference League trophy is Real Betis winger Antony, and that means significantly more than it did five months ago.
The Brazilian winger, 25, escaped his Manchester United nightmare in January as he joined the La Liga side on loan, looking to rebuild a career that had stalled miserably at Old Trafford.
Antony became the Red Devils' second most expensive player ever when he joined from Ajax in 2022 for £81.3 million, but flopped badly under his former coach Erik ten Hag.
