"A win would take pressure off," Olsson is quoted as saying by the Birmingham Mail. "We need to get over that line sooner rather than later and why not on Saturday?
"We need to put on a good performance over 90 minutes, not 75, 80 or 85. That won't do it. We need to do it over 90 minutes and if we do that we'll be alright.
"We will focus totally on that and get ready for it. Of course it will be a different game to City but we will speak about it and we will have time to prepare and make sure we're ready."
Olsson joined West Brom in 2008 from Dutch club Nijmegen Eendracht Combinatie.
