Ajax record signing Daley Blind admits the inflated transfer market has gone "crazy".

The former Manchester United defender returned to Ajax last week for a fee rising to €20.5m. He has been with United for three years.

"I have not determined that (the fee). That was done by the crazy market," he told De Telegraaf.

"I know that expectations will be high, but that is not bad, because I also demand a lot from myself.

"I did not come here to finish, I am 28, feel good and I am ambitious."

He added, "I'm an Ajax fan, as a result, it may be even more exciting to win the title again."
