Arsenal forward Lukas Podolski has admitted that his side's one-sided Champions League defeat by his former employers Bayern Munich capped a bad week for the Premier League club.
The 27-year-old Germany star scored Arsenal's only goal in a 3-1 loss at the Emirates Stadium on Tuesday, leaving the Gunners with an uphill task ahead of the second leg of their last-16 tie at Munich's Allianz Arena on March 13.
Podolski, who spent three years at Bayern between 2006 and 2009, took to Twitter on Wednesday to express his frustration at his side's latest setback.
"I am very upset about the result last night," he wrote.
"We must now stay focus (sic). Another important match on Saturday (when Arsenal host Aston Villa in the Premier League). #Gunner4Life"
Defeat to the Bavarian giants came on the back of Arsenal's FA Cup exit at the hands of second-tier Blackburn Rovers last weekend.
"When you get knocked out of the cup and then lose in the Champions League, there is always a negative atmosphere," Podolski added.
"We conceded stupid and easy goals, that shouldn't happen to us."
