"I couldn't even talk after the game," he admits.
"The fans were fantastic and what more can I say? It was scary!
"It was very tiring but we kept it going, the goals came and the atmosphere was awesome - the best I have played under."
The players could, perhaps, have been forgiven for being deflated at the break when all their efforts had failed to yield a goal, but Marlon says:
"I wouldn't say we were frustrated at half time; we just couldn't wait to come back out and do our stuff again.
"We knew it was going to come."
Marlon reserves special praise for Christian Dailly, who got the all-important second goal, and he adds:
"Throughout the whole time I have been here I have seen him working hard on the field and in training so I am pleased for him."
As for the game in Cardiff, he says:
"We just have to go out there and do what we did yesterday."
