"At half-time we talked about keeping the ball better and being more patient and we dominated play after the break," Redknapp said after the match.
"Things went massively in our favour possession-wise.
"Who knows what is going to happen with regards to the top four.
"Villa are going to be up there. The top two will probably be Chelsea and Manchester United, then will come Arsenal and Liverpool and then Manchester City, Villa and ourselves.
"One of us might break into the top four and it is not impossible for us to do it. It will be hard but we have got some very good players at this club.
"We have a lot of quality but not the sort of squad where 19 to 20-year-olds could come into the first team so it is the same group of people basically."
