Hull manager Marco Silva says the Tigers need to sign three or four 'quality' players before the transfer window closes on Tuesday.
Silva, who has seen his Premier League strugglers knocked out of the EFL Cup and FA Cup in the last week, is concerned about the depth of his squad as he contends with a growing injury list.
Hull have eight players sidelined, including Ryan Mason who fractured his skull last week and Curtis Davies who limped off with a hamstring injury in Sunday's 4-1 defeat at Fulham.
Those injury absentees, combined with the sales of Jake Livermore and Robert Snodgrass, have severely depleted Silva's options and - despite the arrival of five new players during the transfer window already - the Portuguese admits they need more reinforcements.
