The Bulgaria international, who joined on loan from PSV Eindhoven in January, made his second appearance for the Whites and impressed in a more advanced right midfield position.
"It was good to play, it's just a shame about the result," he told fulhamfc.com. "It's nice to be involved and I tried to help both defensively and offensively. People recognise me as a right-back, but I'm comfortable in midfield too. In fact, more recently, that is a position I have played for my country."
