Redknapp managed to finish fourth with Spurs in the Premier League last season.
“I feel we could contend for the title; we have got the players here,” said Redknapp.
“We have to aim for it. We could win the championship.
“Last year, we went in saying we wanted to finish in the top four and if you don’t aim for things, you have no chance.”
“The Champions League is massive – forget budgets – we just want to be there,” he said.
“If we can get into the group stages, we can make an impact. We have good players – some fantastic ones at our club. And they can get better.
“We are going to have to rotate at times – we cannot play the best players all the time. I feel that, if we can bring one or two players in, it will make a difference.”
