Watford boss Sean Dyche has said his side are in desperate need of more attacking options.
The Hornets have drawn blanks in their last three league games and squandered numerous opportunities in Tuesday's League Cup exit to Bristol Rovers.
"We have to score goals and that might mean fresh faces coming in," Dyche told BBC Three Counties Radio.
"That does two things, it puts pressure on the people we've got and freshens up the front line."
Dyche, who took over from Malky Mackay in June, brought in seven new players in the summer, but has so far struggled to fill the void of last season's 27-goal top scorer Danny Graham, who left to join Swansea.
"We're hopeful [of making signings], we're working hard behind the scenes," Dyche added.
"I wouldn't even begin to say the amount of phone calls we've made.
"The guidelines are tough to do the business we want to do, but we keep working towards that end goal which is to get faces in.
"We're active in the loan market, but a lot of the Premier League clubs hold them back until the end of the transfer window, sometimes beyond that."
