MARTIN Olsson believes Blackburn Rovers are already looking like ‘a different team’ under Henning Berg – but has warned that it will take time to reach their full potential.

Olsson jetted off on international duty after Saturday’s 1-1 draw at home to Birmingham as he prepares to represent Sweden in their friendly match against England tomorrow.

The 24-year-old was left frustrated by Rovers’ weekend result but took encouragement from that performance and the display in last week’s 2-2 draw at Huddersfield Town.

Rovers are yet to claim a win in the three games since former Ewood title winner Berg took over as manager.

But Olsson thinks they are already looking much improved as a team – even if it will take time to adjust to new methods under the Norwegian, the full-time replacement for Steve Kean.

“I am frustrated but so is everyone else,” Olsson said looking back on Saturday’s draw.

“We just have to stay positive and keep playing the good football we have been playing in the last two games. Hopefully three points will come soon. I think we look like a different team now anyway.

“I am not going to say anything bad about Kean, he was good in his way as well, but Berg was a legend when he was playing.

“I always watched him play and the way he speaks we listen. We can learn a lot from him because he has been in the same situation. He is always positive.

“It is still very early, he has only been here a week, but he does a lot of tactics like working the whole team instead of the back four.

“It is everyone together and I think it has been shown on the pitch.

“He wants us to play football, not be silly, but to play quick.

“It won’t take a week to change, it will be slow but things are looking good.”

Olsson will face England for the third time in a year tomorrow, in the opening match at Stockholm’s new Friends Arena.

Sweden lost 3-2 at Euro 2012 and were beaten 1-0 in a friendly at Wembley last November.

“I am looking forward to playing against England of course,” he said.

“We had a good game against them in the Euros. It is always good to play England.”

And Martin has formed a left-sided partnership with twin brother Markus in recent Rovers games, something that the duo are happy about.

“If Markus keeps getting the games and I keep playing we will get a partnership, it is good to play with him but it doesn’t matter who we play with,” Martin added.

“Berg wants us to step it up on the pressing. We have conceded sloppy goals, but we will work on that. We need to start winning games.”
