As England set off for their week in the Algarve, there are some questions hanging over England.
Some of England’s positions are locked down Owen Farrell at fly-half, Billy Vunipola at number eight, Maro Itoje at lock, the back three however is more complex.
England are missing Anthony Watson and they have a wealth of talent, Ollie Thorley the latest man to earn a place in England’s squad.
One thing that did let down England in the autumn was a failure to boss the aerial battle, Elliot Daly is a fantastically talented player but he was far from his best in the 15 shirt.
Against Ireland defusing high balls and bossing the aerial space will be key, Jonny Sexton is a good kicker and Conor Murray is arguably the best box kicking scrum-half in the world.
Whoever lines up at fullback for England will have plenty of high balls to deal with.
This is why England have to pick Mike Brown. Brown is a master of the high ball, he gets up well and more often than not comes down with the ball.
His abrasive, aggressive nature give him the edge in the contest and make him the safest option to limit Ireland attacking England from above.
Brown does not have the fast feet to match his Wasps counterpart and he lacks the playmaking ability but against Ireland his safe hands and unquestionable passion make him England’s best shot at gaining an all important win in Dublin.
