Bayern Munich captain Philipp Lahm was not surprised by his side's stunning 4-0 win over Barcelona in their UEFA Champions League semi-final first leg.
The German champions have one foot in next month's final in Wembley after destroying Barcelona at the Allianz Arena.
Thomas Muller's double and a goal apiece from Mario Gomez and Arjen Robben earned Bayern a healthy advantage to take to Camp Nou next week.
Lahm admits Bayern targeted Barcelona's weakness in the air with two of their goals coming from set-pieces and the full-back hailed his side's defensive display to restrict the Spanish side to one shot on target throughout the 90 minutes.
"Of course I can comprehend what happened. We have the potential to beat any team," said Lahm.
"It's well-known that Barcelona have problems in the air. Defensively we were close to perfection, that was the key."
Bayern winger Franck Ribery believes their hard work in the game paid off and he was always confident they had the players to score against Barcelona.
"To get such a result, we knew we had to work together," noted Ribery. "Apart from that, we knew we had a striker who could score."
"We're very happy. There is one game left but I think we performed well tonight."
Jacobson, the stand-in captain, chose a perfect time to grab his first goal of the season when he whipped a 20-yard effort over the Oldham wall and high into the net four minutes into the second half.
Both of these sides guaranteed League One survival last weekend and it was Shrewsbury who started the brighter.
They should really have forged an early lead but Akwasi Asante, having pounced on a slip from Jean Yves M'Voto, fired wide from the edge of the area with only goalkeeper Alex Cisak to beat.
Oldham, whose manager Lee Johnson made eight changes to the team which beat Crawley last Saturday, then created a stream of chances.
Top scorer Jose Baxter twice stung the gloves of goalkeeper Chris Weale, who also saved sharply from Kirk Millar.
Then Baxter squandered a golden chance right on half-time when he headed Lee Croft's cross wide.
But Shrewsbury grew increasingly dominant in the second half and might have added to their lead when Jon Taylor rounded Cisak but fired against the near post from a tight angle.
Then Connor Goldson headed a corner just off target but Jacobson's fine strike proved enough to lift Shrewsbury above Oldham in the lower reaches of the table.
