"It was a big game and you want to give yourself every opportunity to play ... to play in a final means a lot, for myself and this team. I was confident I could play and that's why I started, but it unfortunately didn't last as long as I would have liked."
Carter, who expects his injury will require only two weeks of rehabilitation, admitted that Saracens had been worthy victors and he highlighted the impact of his opposite number, the England fly-half Owen Farrell.
"Saracens put us under a lot of pressure and we weren't able to get our game going," Carter added."They took away our time and space, not helped by the greasy conditions.
"We had high hopes going into the game, the team has been playing well in the competition, but we met our match in Saracens tonight, they really outplayed us.
"We thought that if we could stay close to them on the scoresheet we could give ourselves a chance, but when Owen got those penalties at the end, we realised the game was slipping away from us.
"He played well. Saracens have had a tough four years in the European Cup and after getting so close over three, four years, they deserve it tonight and he led the way for them.
"Strategically, Farrell put them at the right end of the field and kicked those goals which plays an important part of finals footy."
