Signed for £11m in the summer, Petr Čech was an absolute bargain.
The goalkeeper, who is 33, has been superb for the Gunners since his unfortunate performance against West Ham United on his Premier League debut. He exuded calmness throughout a huge game on Tuesday night, keeping Bayern at bay at the Emirates Stadium.
Arsenal sealed the win at the other end, but Čech built the foundations for a famous win. A great save stopped Thiago Alcantara from scoring early on, and another denied Robert Lewandowski in the second half.
After years of merely getting by and having men who split opinions of fans, the Gunners finally have a goalkeeper of indisputable quality between the sticks.
