Wolverhampton Wanderers reportedly failed in a loan move for Watford forward Stefano Okaka on deadline day.
According to the Express & Star, that led to a late offer for Okaka, who had started the campaign in the Watford starting lineup and netted a goal against Liverpool on the opening weekend.
The 28-year-old has not featured since that game, but it has been claimed that the Italian made the decision to remain at Vicarage Road rather than gain first-team football at Molineux.
Wolves are still able to sign free agents but as it stands, Leo Bonatini is the only forward in Nuno's squad heading into a four-month period before the start of the winter transfer window.
The West Midlands outfit currently sit in fourth place in the second-tier standings.
