Carragher sees changes to established top four
He told the club's official website: "I think Man City are looking very strong - Tottenham as well. City have got some great players, world-class players, and I am sure they will be buying more in January so they are going to be a massive threat.
"Aston Villa and Everton are always up there too so I think it will make it a little bit more exciting this year.
"The top four places will certainly be up for grabs but we want to make sure we are up there. I think with the other teams becoming involved hopefully they will take points off the other big sides as well."
