The powerful forward goes into his third spell with the club having scored 19 goals in 54 games across the 2018/19 and 2019/20 seasons.
‘Macca’ also praised the club’s facilities as he prepares to impress once again.
McDonnell said: “I came down to the ground and the facilities look unbelievable, so I just cannot wait to get back going.
“The club is going in the right place and is only going one way, which is up. It is like a professional club and the changing rooms look absolutely brilliant.
“I didn’t leave on bad terms when I went to Belper; we had a couple of conversations, but it didn’t work out that time.
“As soon as [Craig Parry] called me and asked me to come back it was a no-brainer really; I had a few options but Worksop is the place I want to be and I cannot wait to get back under way.
“When we spoke, he sold it to me as we play all-out attack and we press high, which is exactly how I play, so I am hoping I can score loads this year.”
McDonnell enjoyed a double-winning campaign in his first stint with the Tigers before helping Worksop to compete at Step Four of non-league football.
The forward reminisced about his previous periods in a Tigers shirt and states that he is excited to get back in front of a fanbase close to his heart.
“When we won 22 games in a row – I don’t think it’ll ever be matched in the NCEL – it was a special moment in probably my best year in football,” continued McDonnell.
“Then coming back under Kyle and he had a lot against him that year in charge. But I think we had quite a decent season considering the behind-the-scenes struggles we had and with it being the club’s first season at a higher level for many years.
“The fans bring so much out of me, and I adored them over previous spells. I want to get back on the pitch and pull on that shirt again.
“Even when I played for Belper against Worksop last year, they were shouting my name and it was special, and that’s why I cannot wait to be back because the club is in my heart.”
