Wales stand-off James Hook believes the Ospreys have demonstrated they are a quality outfit after their Cup final victory over Leicester.
Hook set up two tries and kicked 13 points in the 23-6 victory over the twice European Cup winners on Saturday.
"I think there is huge potential in this Ospreys side. We proved it out there by getting the result," Hook told The South Wales Echo.
"We all know what we are capable of. It’s all about keeping on working hard and trying to prove ourselves."
The majority of the Ospreys’ side were also involved in Wales’ RBS 6 Nations Grand Slam including a comprehensive victory over England at Twickenham.
"It gives you confidence to realise you can get the victories here," Hook enthused.
"A lot of the boys played in that England game.
"And quite a few of us came here last year and lost to Leicester in the EDF final. Everyone came back here with a determination to win this time."
