Liverpool hero Sander Westerveld says the club was right not to buy a new goalkeeper.
Westerveld was also asked whether the Reds did the right thing in not signing a new keeper from the Championship before this Friday's domestic transfer deadline. They were linked with Stoke's Jack Butland.
Speaking to the BBC, the former Netherlands international said: “A club like Liverpool always wants to improve. I was the big example of that, winning five trophies but still being replaced by two new keepers. So they are always looking to make the team better, but if they could've brought in someone better than Adrian they would've brought them in probably.
"They couldn't, so that shows how much faith they have in Adrian. I don't think it would've been great to bring somebody new in because Alisson is back in four to six weeks so to bring in somebody now, who doesn't know the team and put them straight into a derby, there would be a lot of pressure. I think the best option was to stick with Adrian."
He added: “We had an international break in between so he [Adrian] had a little time to train hard and put all the focus on this game.
"This is the game for him to really show his character. There will be a little bit of pressure but we've seen and everybody knows as well that he can play great games, he just has to show it.
"The most important game of his career is always the next one. This is a great game for him. If he plays well, keeps a clean sheet or makes some match-winning saves, he's the big hero for a long time coming."
