Ulster found the Ospreys defence hard to counter

He also said that the team will have to work hard to repair the damage after two successive home defeats.

''It's very strange for us after the last two seasons where we had a great record at Ravenhill,'' said Wilson.

''Now we seem to performing very well away from home, but our home form has been disastrous.''

Wilson was obviously shattered at the lose and the fact that Ulster are only mid-table.

''We were all extremely disappointed at the result. We just seemed so flat throughout the game.

''We never really got going. Even when we were 14-0 up at half-time, one could argue we didn't deserve to be in that position.

''Nobody could understand the reason why. We will watch the video on Monday and re-assess things then.

''We were clinical when we got into the opposition ''22''. But on saying that, if you score the points, you also have to defend your line as well.

''Unfortunately we didn't do that as we were slipping off tackles. Both our defence and set-piece play were poor and you cannot really perform without the structures.''

Wilson then spoke of the incredible 10-minute period after the restart when Ulster leaked 21 points.

''It was a real disastrous period for us,'' said Wilson, who has definite international aspirations this season.

''We just seemed to shut down and fall asleep and they hit us with those killer blows and we found it difficult to come back.

''But all credit to them. They have improved from last season with a very attacking back-line who showed what they could do with good ball.
