What's gone wrong for Johnny Sexton this 6 Nations?

Johnny Sexton's Six Nations campaign has been one to forget.

The World Player of the year looks a shadow of himself and a complete different player to his 2018 form. Hauled off today after a laclustre performance, Sexton cut out a frustrated figure with many passes not going to hand, kicks straight out into touch and some poor defence.

Sexton has only managed 1 full game this 6 Nations, the defeat at home to England, but his performances have not been up to his usual high standard and fans are starting to vent their frustrations.

Jack Carty has done more right in 10 minutes than Sexton did the full game. Players have off days - we have to be willing to pull them when they happen. #WALvIRE

Half-back partner Conor Murray has also struggled for form which could be a key contributer, but is this a sign for Ireland fans to be worried ahead of September's World Cup.
