Former Ireland international Stephen Ferris thinks teams have adapted to Ireland’s tactical approach and says the body language isn’t positive from the men in green.

Wales powered their way to a grand slam with a comprehensive 25-7 victory over the holders at the Principality Stadium, where the visitors only got off the mark with a Jordan Larmour try in added time.

Wins over Scotland, Italy and France were bookended by defeats and Ferris says the signs were there all championship that things weren’t quite right.

"I questioned Ireland’s form after the first game against England," he told RTÉ’s Game On. "France didn’t pitch up at the Aviva Stadium last weekend even though everyone was talking Ireland up.

"I thought the referee was pretty harsh on them on a number of occasions, but in saying that, Wales were by far the better team.

"They [Ireland] were absolutely blown off the pitch."

The 35-cap international thinks the approach adopted by Ireland was the wrong one against a fired-up Welsh side  -  "today wasn’t a day to go over to Cardiff, roll up your sleeves an arm wrestle" and says the off colour performances from the leadership group was stinking.

"Rory Best, Johnny Sexton, Peter O’Mahony, they all come out and say they expect standards of each other, what the coaching set-up expects and they have been so far off those standards this Six Nations," he said.

"As a collective they have been off the mark, but individually they have too. Today was a nightmare for Johnny Sexton. Conor Murray couldn’t get himself into the game. Rory Best didn’t have his best game, Peter O’Mahony was non-existent, as were a number of other players."

Despite winning 23 of their last 26 games, Ireland conclude the Six Nations campaign on the back of a number of disappointing performances and says it poses more questions than answers with the World Cup on the horizon.

"Johnny Sexton walked off the pitch looked like a man in a world of pain"

"Are teams starting to figure out Joe Schmidt’s game plan out? They don’t seem to be kicking the ball as much as they have done over the past couple of seasons.

"They just don’t look like they are enjoying their rugby. Johnny Sexton walked off the pitch looked like a man in a world of pain."
