So, what can Liverpool fans expect from their new No 1? But it's the start of what's going to be a busy campaign for us.
Whilst taking a goal-kick shortly before the interval, the Brazilian slipped, injuring his calf in the process.
Liverpool goalkeeper Alisson Becker was on Monday ruled out for "the next few weeks" by coach Jurgen Klopp after suffering a calf injury in their 4-1 win over Norwich. He last played for Middlesbrough and is now a free agent.
Lonergan, most-recently of Rochdale (on loan from Middlesbrough), trained with Liverpool throughout the summer, amid a goalkeeping crisis. "But he is not in for the next few weeks". But Caoimhin Kelleher is now in his final steps for being completely back'.
"I'm not anxious at all about how he will do it in the long term, but in the short term the problem is just that he came here with no club when we signed him", Klopp said.
'He was in with us. He's a brilliant character, a really nice lad and helped us a lot in the pre-season and now we made a decision to work together with him'. "It's a calf injury which takes him obviously out for a while", he told Liverpool's official website.
Every player wants to play for his country and I treasure all of my Ireland caps, but it seems unfair that Mane was still playing for Senegal in the middle of July and then has to come back to Liverpool and play in the Premier League a few weeks later.
The Spanish shot-stopper has arrived at Liverpool without a pre-season under his belt and though Klopp insists he has looked sharp in training, he admits there is a need to take extra precautions to make sure he too does not pick up an injury.
