Ulster skipper Rory Best says he and his Ulster team-mates are "bitterly disappointed" by their 27-9 defeat at the hands of Saracens in their first European Champions Cup Pool 1 game in Belfast.
Last week, another of the top English sides, Wasps, defeated Leinster 33-6 in their opening match of the competition.
The Premiership leaders scored four tries to secure a bonus-point success at Kingspan Stadium.
"We are a lot better than we showed in that match. Sometimes we played some decent stuff, at other times we were so far off," said Best.
"They had four scoring opportunities and scored four tries so you have to give them a lot of credit for the way they played."
