Olsson: West Brom are fully deserved of their current league position
The Baggies have been one of the surprise teams of the season so far with the help of a 3-2 success over Arsenal at the Emirates Stadium.
But central defender Olsson believes Albion deserve their lofty position after recovering from a six-goal mauling at Chelsea on the opening day of the campaign.
He said: "We are not going to apologise for being sixth because we deserve to be where we are.
"We need to keep going and keep believing in our game plan but if you win at the Emirates, you shouldn't fear anyone."
Olsson added: "When you look back at your career, you remember going to places like Old Trafford and the Emirates.
"The way we're playing at the moment makes me confident and inspired to go there.
"We've earned the right to go there (Old Trafford) and give them a test."
