Jamie Carragher has welcomed defensive competition at Liverpool from new teammate Martin Skrtel.
"Obviously, it is competition at the back for me and the rest of the centre backs but that can only be a good thing because it keeps you on your toes and you have to prove over again that you are good enough to stay in the team.
"That's what I'm looking to do and I'm sure that the other centre-backs will be looking to do the same.
"The new lad coming in will be looking to get games so it's always healthy competition."
