Victory on the final day will guarantee the east Londoners a top-half finish and Wales midfielder Collison plans to make sure there is plenty to cheer come full-time on Sunday afternoon.
He told whufc.com: "We're really looking forward to the Reading game, back at home, in front of our fans and hopefully we'll have reasons to celebrate. It has been a magnificent season for us. Safety was the main aim and we'll look to finish as high as possible and put on a real show for our fans.
"Reading have been our bogey team over the last two seasons and obviously we're going to try to send out a statement and score as many goals as we can."
