ALISSON impressed Liverpool boss Jurgen Klopp without kicking a ball.
Liverpool spent around £67m to lure Brazil international Alisson from Roma last month as a replacement for error-prone Loris Karius.
He will be heavily scrutinised due to the size of the transfer fee and Karius’ high-profile blunders last term.
But Klopp believes Alisson has the mentality to thrive under pressure.
“The good thing is from the first day he has been very stable and calm, but then again we already knew a few things about his personality when we signed him,” Klopp said.
“And apart from catching balls, that helps massively.
“You need to have the right personality for that very difficult job. And obviously he has that.”
Alisson is set to make his debut for Liverpool against West Ham (1.30pm).
The Reds will have to shake off the disappointment of losing May’s Champions League final if they to mount a Premier League title challenge.
“It is no problem,” Klopp told Sky Sports.
“There are bigger problems in life than losing a Champions League final, so we all have bigger problems than losing a Champions League final.
“We tried everything, it did not happen, so that is all. It is a long time ago and a waste of time having that in your mind. So no problem, we go again.”
Liverpool new boy Fabinho faces a fight to be fit for the Hammers’ visit.
The £43m signing from Monaco picked up a knock in the 3-1 win over Torino on Tuesday.
Georginio Wijnaldum could feature in the defensive midfield role either with new signing Naby Keita and James Milner either side.
Xherdan Shaqiri, captured from Stoke, is likely to be on the bench.
Dejan Lovren is unlikely to feature as he only returned to training recently, following his involvement as Croatia reached the World Cup final.
Captain Jordan Henderson is also unlikely to play after figuring in the England side that reached the final weekend of the tournament, although he did appear in Tuesday’s friendly with Torino.
