Liverpool goalkeeper Loris Karius is aware the competition for places means he cannot afford to be complacent having won the first battle to be Jurgen Klopp's first choice.
The German was selected ahead of the established Simon Mignolet, who has not had a worthy rival since joining the club three years ago, for his Premier League debut in the 5-1 win over Hull.
Karius was signed by Klopp from his former club Mainz for £4.7million and the assumption was he would become the new number one.
However, a broken hand in pre-season delayed his availability but after a comfortable midweek run-out against Derby in the EFL Cup he was handed the chance to stake his claim.
