KEEPING a lid on a "euphoric" win over West Coast will be Brisbane Lions coach Leigh Matthews's next trick.

His pre-match address was cited by players as the inspiration for the Lions' 27-point last round boilover against the defending premiers at Subiaco.

And it seems Matthews' oratory skills will be tested again before the Lions attempt to back up against Melbourne at the Gabba on Saturday night.

While Matthews admitted the shock last-round win had given his rebuilding Lions new-found self belief, the Brisbane coach also demanded a "neutral emotional state" against the Demons.

That will be easier said than done judging by the Lions' frenzied reaction to the Subiaco win, led by Matthews himself.

Matthews admitted even he wasn't confident that his side could beat the Eagles - and his relief was evident at full time when he ran onto the field like an excited teenager to congratulate players.

And it would be tempting for Matthews to get carried away further as he prepares for a fortnight against lowly opposition - Melbourne and Carlton.

But the four-time premiership-winning coach was having none of that.

"The challenge every week is to get yourself into your neutral emotional state," Matthews said.

"If you have lost badly it's a challenge and if you've had a euphoric win it's a challenge.

"In pure player talent Melbourne and Carlton will be fielding similar teams (to Brisbane).

"It (the Eagles upset) should be excellent (for morale) but it's come and gone.

"The emotion of last week needs to start subsiding, and we are into the next phase which is Melbourne on Saturday.

"We've got to produce that again next week.

"(But) if you tackle well and play boldly, bravely and passionately you give yourself a chance."

Matthews tried to play down his pre-match role against West Coast despite being lauded by players, saying "you do what you do".

But the Lions mentor couldn't hose down the effect the Eagles upset had on his young brigade featuring debutants Will Hamill and Matthew Leuenberger.

"I think it will help medium-term, long-term - certainly next Saturday night," he said.

"Deep down the belief that they belong in this competition and play well in this competition is what you want all players to achieve.

"Saturday night would help many that haven't maybe had that belief previously."

Matthews also dipped his hat to an aspect of the Lions game that was much maligned during their recent seven-match win-less run that came to a shuddering halt in Perth.

"We picked the team to try and increase our running power, and I think we did that," he said.

"We had a look early in the year of being a pretty quick team.

"In the last couple of months we looked like a pretty slow team.

"But just having Luke Power back (from injury) helps (running power)."
