The Swede is now enjoying a first team run after making his debut against Norwich City.
"I really enjoyed my time there, and it was a good two months or so," he told fulhamfc.com of his time with the Hornets. "I got to play regular first team football and I learned a lot from that.
"I'm very thankful that they gave me the chance and hopefully I can just keep on going now. It's a big challenge to step up and play with the big boys in the Premier League, but it's what I want to do so I'll have to get my head down and hopefully as a result I'll get more chances to play."
