And now the Wanderer's striker hopes McAllister will be impressed enough to make a bid for him when the transfer window opens again in January.
Holdsworth said: "This is a great chance for me. It's another instalment in the chapter of events I have gone through during my career.
"Coventry are looking to push for the play-offs and achieve promotion and I hope to help. I can bring a lot of experience to the side.
"I was impressed with what I saw when I trained with the boys. Everybody made me feel welcome.
"This is a great opportunity for me to impress Gary McAllister and the Coventry fans and then maybe things can go from there."
