Hull defender Curtis Davies says the Tigers need help in the battle against Premier League relegation.
Hull lie 19th in the table after Monday's 1-0 defeat at Middlesbrough.
They had only 13 senior players to choose from on the opening day of the season and signed six in the last two days of the summer transfer window.
"Our signings have done their bit but they were last minute," said Davies. "I don't believe the manager had time to explore all of his options."
Hull have scored only 11 league goals this season, fewer than any other team in the top flight.
