To be fair, considering it was KWP's debut game and he had to be nervous, to take on strong players and do as well as he did, he performed very well. If we look at a players ability in a game against the odds, as he was, maybe KWP was right in getting MOTM. But if you regard the players for their ability'performance only, then for me it was Eriksen.
But you know, on your debut, getting MOTM and doing well, it will set you up and boost your confidence, which can't do too much harm.
