Al-Ettifaq coach Steven Gerrard says they need to buy in January.
Al-Ettifaq are winless in eight matches and sit eighth on the Saudi Pro League table.
Pressure is growing on the Liverpool and he said, "We need to show in this window, and also the summer window, that we mean business and we want to be competitive at the top of the league, and not where we are at the moment.
"It's a collective thing - the players here and now need to give more, and people need to step up and, at the right time, we will hopefully be able to make significant changes to the team and the squad.
"Hopefully at the back end of January you will see a different, stronger and more competitive squad.
"We have already had important meetings at Al Ettifaq in terms of mid-season updates and where every individual is, and where the group is at. The message, in summary, that we have sent is that we need to be aggressive, we need to be ruthless, and we need to make a lot of changes to make this team more competitive."
