Mignolet's position as the number one goalkeeper for Liverpool has been in doubt for a while following his shaky performances last season and the arrivals of the promising Karius and veteran Manninger to Anfield this summer has put the Belgian international under more pressure.
However, Mignolet has stated that he is not fazed by the added competition from the summer arrivals and has explained that he actually welcomes the pressure.
He told the Liverpool Echo: "When I signed that new contract the club said that there would be fresh competition. That is the normal thing - that you have three competitive goalkeepers.
"Besides Karius we also have Alex Manninger and all three of us get on well. I have already learned a lot from Alex. He is someone who has worked throughout Europe and gives me a lot of confidence. I've had competition in my entire career and that is normal when you are at a top club.
"There should always be competition, but only one goalkeeper can play. I can only look after my own performance on the pitch. The arrival of a new goalkeeper has changed nothing. I work hard, keep both feet on the ground and have confidence in myself."
