Antonio Conte felt Chelsea were unlucky to miss out on the Carabao Cup final.
Arsenal came from behind to beat them 2-1 in the semi-final second leg at the Emirates Stadium, scoring two fortuitous goals after Eden Hazard had given the visitors an early lead.
The Gunners equalised when Nacho Monreal’s header ricocheted in off both Marcos Alonso and Antonio Rudiger.
And a deflection off Rudiger teed up Granit Xhaka to score Arsenal’s winner in the second half.
“We had great desire and great will to play at Wembley,” said Blues boss Conte.
“We started the game very well, we scored, and then we conceded a strange goal with a deflection and for sure we conceded two strange goals and were unlucky.
“They were a bit lucky in these two situations but we have to praise this Arsenal team.”
Conte also described an injury to Willian as “decisive”.
The Brazilian limped off with a hamstring problem in the first half and was replaced by recent signing Ross Barkley, who came on for his debut.
Meanwhile, Arsenal boss Arsene Wenger insisted his side fully deserved to win and that their switch to a back three was the decisive factor.
