Carragher plays his final game this weekend.
He told liverpoolfc.com: "I think it does a little bit more, he's obviously been a top manager - his record is there for all to see. They've got another top manager in David Moyes, I'm sure he'll do a great job there. I'm sure everyone is looking at it and seeing how it will go; maybe it will give other people a chance to get in there if there is maybe a bit of uncertainty at the club. But Manchester United are probably aware of that as well so I'm sure they'll be doing everything to stop that."
