I have to say, I only see us play live twice every four months or so, but that means I can probably see improvement more sharply than those who see the matches ever week. Mariappa has improved massively from what I saw against WBA. He was confident on the ball and pretty creative in comparison to what he used to do, good passing, got forward alot and got into good positions where he could have a couple of shots! On top of which, disregarding his last minute lapse, had a good game defensively too. I was genuinely impressed, he looked a very accomplished player.
He seems to have come on leaps and bounds since the beginning of the season.
