Anger management could prove the key to who wins this year’s Six Nations title.

England’s meeting with Wales at Twickenham won’t be decisive, but it is likely to give a very strong indication of where the crown is going.

Should England win then only France could deny them at Twickers on March 19 – assuming of course that France are victorious against the Scots on Sunday.

If the Welsh can take a win away from London on Saturday then they are would appear to be almost there as they complete their campaign against Italy in Cardiff.

The winner will have the ball firmly in their court going into the final round of matches and personalities could hold the key.

Certainly Chris Robshaw will want to have an important role after his World Cup ‘mistake’ allowed Wales a 28-25 win at Twickenham and sent England crashing out at the group stage.

It could be that the battle of speed and power could have the big say.

England’s Billy Vunipola and Wales’ Taulupe Faletau will provide an earth-shaking showdown with no quarter given and no doubt both players smiling their way through an epic struggle.

The half backs provide a real conundrum as the partnerships are not set in stone.

But the big question is who will have the big-game mentality to step up and run the show?

Gareth Davies or Rhys Webb are in the running to support Dan Biggar who will want to take the lead.

They are likely to face Ben Youngs and George Ford who have their own reasons for wanting to show once and for all why they should be the first choice to new coach Eddie Jones.

However, the big battle is shaping up to be the men at either end of the field.

Whether they come into contact very often is a moot point, but the two team’s respective Mr Angrys will be those wearing the No15 shirts.

Mike Brown, for England, and his Welsh counterpart Liam Williams both wear their hearts on their sleeve and are both very capable of setting the tone for the contest.

I must admit I have a lot of time for Brown.

In one of those pub discussions between rugby league fans a while back the question was posed who would you take from union to play in the 13-a-side code.

Once the obvious selections of Ford and Owen Farrell, given their rugby league heritage, were put to one side I had to opt for Brown.

His passion, tenacity and refusal to take a backward step certainly appeals and I would love to see him follow another Mike – the legend that was Lampkowski– from playing in the white of England at union into wearing the red, white and blue of Wakefield Trinity.

Somehow I think that Super League’s salary cap, or more simply the salary Brown is paid by Harlequins, renders this particular daydream instantly redundant.

Seriously the influence of Brown and Williams could be what changes the tide at Twickenham.

However, if you want to place a bet on who will be the fastest man on the pitch, have a punt on referee Craig Joubert.

If the South African makes another rick like he did in Scotland’s World Cup clash with Australia, he is certain to embarrass all the backs on show with his pacy sprint to reach the changing rooms.
