Olsson has revealed his 'connection' with Gareth McAuley played a huge part in him deciding to pen a new four-year Albion deal last week.
Olsson told the WBA website: "I finally feel I've been able to get a good partnership at centre-half.
"I very much enjoy playing with Gareth and I hope our relationship can be a long one. One of the reasons I have re-signed is that I really love playing with him.
"He's a good guy as well and that makes it easier to connect on the pitch.
"It's normal when you play next to each other on the field to talk a lot and be friends. I definitely feel a connection with him."
