Liverpool boss Jurgen Klopp has sought to rally his players as they fight to snap a midseason form slump.
Liverpool endured their worst sequence of results for almost two years over the Christmas period, with two points from a possible nine.
"In good times everybody thinks our owners are really generous," said Klopp. "In bad times everyone thinks they are really tight but they are not. They are absolutely concerned about the club, the success of the club and understand how we have it.
"So they see exactly the same things I see about the necessity (to bring in) players and things like this. It is not that I say: 'By the way, a centre half would be really nice!' and they say: 'Wow! A centre half! Really, why?' It is all clear. It is all on the table. We work on that, you can imagine.
"But it is the situation. On top of that we have January and it is not the easiest transfer window. A supporter may look at it and think 'they need a centre half and the other team has a good one so bring him in.' My job is to really to make the players we have here as strong as possible.
"Would one centre half help and sort all our problems? Maybe for a game or two but then he could be injured as well. We don't know. We have to work together and we did that so far and it is a the trickiest situation you can imagine – three senior centre halves and they are all injured."
