Bayern Munich midfielder Thiago Alcantara is wary of the threat Arsenal pose as the duo prepare for their Champions League second-leg clash.
The Premier League club travel to the Allianz Arena with a hard task to turn around a 2-0 deficit following the first meeting two weeks ago.
But ahead Tuesday's clash Thiago has admitted that the tie isn't over despite the convincing win at the Emirates in the first-leg and believes Arsenal can cause the Champions League holders real problems.
"This Champions League round against Arsenal is not decided, it is true that we have an advantage but this Arsenal team is very dangerous," he told Sky Sports.
"Last season Arsenal won in Munich and that is a warning for us, but this squad is focused on the match as we know it won't be easy.
"We know we are developing a big season, but you can't have that sort of confidence in Europe. To let the two-goal advantage from London go would be a disaster - but we are not thinking about that situation."
It may be a result that Arsenal live to regret after Mesut Ozil missed a penalty when the scores were goalless and Wojciech Szczesny received his marching orders.
Second-half goals from Toni Kroos and Thomas Muller secured the result but former Barcelona start Thiago insist that Bayern will go into the match with a clear head.
"Pep [Guardiola, coach] has demanded that we forget the first match and go out and get a goal and win from the first moment.
"We know Arsenal will attack but that could be positive for us."
Can Arsenal shock Bayern and qualify for the Champions League quarter-final this evening? Have your say below!
