Trap clearly doesn't believe in creative central midfielders, that's his system. And yes it hasn't deliverd world class results, but given the players in the Irish setup, including Andy Reid (who by the way has never played in the Champions League, compared with Pirlo, De Rossi, Zambrota, Buffon, Cheilini, Grosso and so on) we have got good results.
As for not contributing to the team, Whelan has scored two vital and very skillful goals in this campaign which most strikers would be happy with. To say the game passes him bye is a nonsense. He's scored more goals in the campaign than Duff, McGeady, Hunt and Doyle, our creative players.
Here's a good article I came across on Trap for those who want to know more about his football philosophy.
