The 24-year-old, Albania-born winger, who enjoyed a successful loan spell with the Saddlers during the first-half of the 2017/18 campaign - where he netted three times in twenty first-team outings - is keen to get the season underway.
Speaking via the club's official website - Saddlers.co.uk - Zeli said; "I’m buzzing to be back. I felt like I did well when I was here on loan. I had a great connection with the fans and they were really positive towards me. Every time I got on the ball, they gave me a boost. I know the boys – they’re brilliant – and I’m looking to meeting the new boys too. I can’t wait to get started."
