Feghouli, having signed for the Irons from Valencia, quit London over the summer for Gala.
He told Foot Mercato: "I arrived at a club where I was not really given a chance. I was injured before the first day and I was away for a month and a half. When I returned, I did not play until the winter transfer window.
"I was not given a chance, despite my return and the fact that I made a few goals. It did not go well. I almost left the club in the winter transfer window.
"I had opportunities and wanted to bounce elsewhere as I was not given a chance. The club did not want to let me go. In the end, I played little.
"So it's a bit of mixed feelings because in my statistics, it was not too bad for the little I played. But in terms of playing time, it was not at all what I expected especially in terms of the games played and the chances that was given to me by the coach.
"It's like I'm expecting something super good by joining the Premier League, West Ham, their new stadium, etc. But in the end, it's not been an adventure at all."
