Nuno Espirito Santo says it's "obvious" that he needs to sign new players for Wolves this January after they made it four games without a win on Saturday.
Newcastle bagged a 1-1 draw at Molineux despite their crippling injury problems, and that result led Nuno to admit that Wolves are struggling.
Wolves have used just 19 players in the Premier League this season and they've looked tired at times over Christmas after a long and busy season already thanks to their Europa League involvement.
Having already allowed Patrick Cutrone to join Fiorentina, Jesus Vallejo will return to Real Madrid this month and Nuno knows numbers are getting thin.
"It's obvious that we must bring players," he said, with Wolves seventh in the table. "It was not the best game, it was difficult, not many spaces, but the final delivery should be better.
"We are working and hopefully things work out and we can solve it. We need solutions, we need more than specific positions, players that can bring us different situations, that can help us in these kind of games.
"I'm not happy because we didn't perform like we all wish, like we expect and should do. I always want perfection and sometimes days like this happen."
Nuno insisted fatugue was not a factor in their draw with Newcastle, as they had several chances to win the game after Leander Dendoncker had cancelled out Migeul Amiron's opener.
Wolves are now in ssventh in the league table, remain in the Europa League and have an FA CUp replay against Manchester United this week to try and stay alive in that competition as well.
Newcastle also have a replay to deal with during the week as they face Rochdale without a host of injured played, with the list growing on Saturday as Paul Dummett and Dwight Gayle suffered hamstring injuries while Joelinton played on with a groin problem.
"I would think it'll be a big impossibility they'll be ready. Is anyone back? We'll see what the under-18s have got," said boss Steve Bruce.
"The resilience of the squad has always been there. They are a determined lot and a good lot to work with.
"They roll their sleeves up and a have a go. Yes, we lack a bit of quality and pace and power in certain areas, but you can't fault the way they go about their work."
