Liverpool left-back Emiliano Insua knows he will need to increase the level of his performances at every opportunity as competition for places becomes more intense.
The 20-year-old Argentine started the Reds' first seven games of this season and impressed in the injury absence of Fabio Aurelio and lack of form of Andrea Dossena.
But with Aurelio returning to action in the Carling Cup win over Leeds on Tuesday, Insua knows he cannot rest on his laurels if he wants to keep a place in Rafa Benitez's team.
He told Liverpool's official website ahead of Saturday's clash with Hull City at Anfield: "The chance to play regularly has been great for me.
"Fabio's injury gave me an opportunity to play and I have done my best to make the most of it.
"There is a lot of competition for places here with Fabio coming back and Andrea as well.
"It is a big challenge for me and I am enjoying it. Every game I have to show the manager that I deserve to stay in the team.
"When there are players pushing for your place you have to play even better each time you are selected.
"The fact that Rafa has faith in me has given me a lot of confidence. Every day he is looking at my game and helping me develop.
"I have learned a lot from him but I know I still have a lot to prove."
