I dont know who will win but I do know that the semis are going to be brilliant. Theres a good chance of Leeds vs Huddersfield and Wigan/Wire vs Saints that would be pretty impressive and is a good chance should the "favourites" win all games.
I think going in as "underdogs" actually makes me more relaxed theres slightly less pressure as the team arent expected to win and that should bring out their better side. The last couple times we have met Wire in the cup we have been the favourites that could play a big part in the teams mentality. At the end of the day we don't know until the came finishes at about 6pm on Saturday.
I'll be happy as long as its a fair match and the team who plays best wins and not the team that gets lucky from the referee seeing/missing things.
