Hornby was sent out on loan to Belgian side KV Kortrijk for the 2019/20 campaign.
"When I learned of KV Kortrijk's interest, I looked up things like the club's past, who played here and after an enlightening conversation with trainer Yves Vanderhaeghe, who clearly explained his plans for the team and me, I thought it was a great opportunity to come here.
"I also checked with Yannick Bolasie about the Jupiler Pro League and told me that I would be surprised about this competition. When he arrived at Anderlecht, he was also surprised about how intense this competition is.
"After a few days of training at KVK, I immediately knew what he meant: the level here is high, the coach is demanding, I am now even more convinced that I have made a good choice, here I will be challenged again."
