Benitez: Changing Mourinho's ways will take time

The former Liverpool manager admitted Inter were below par against the Europa League winners, who triumphed through goals by former Arsenal forward Jose Antonio Reyes and Argentina striker Sergio Aguero.

Benitez said he wants to change some of the things put in place by his predecessor Jose Mourinho but needs time to do so.

"Some things we will need to do in the same way as we did before and change the way we do some other things,'' said Benitez. "It's clear we will need some time but how long you never know. We have not had much time since the World Cup with the players. We were not at the level we needed to be against a team that was physically stronger and very good tactically.''

Benitez added that Inter's Champions League group with Tottenham, Werder Bremen and FC Twente was potentially dangerous.

"It's a really difficult group,'' he said after the match in Monaco's Stade Louis II. "There is not a big difference between the teams and that can be dangerous. This will be very tough.''
