Tonight Arsenal must show that they are the real deal

To put it simply, when Arsenal take on Porto later tonight in the 2nd leg of the UCL Round of 16 tie, they must show that they belong at the top level. Over the last year and half, Arsenal for all effects and purposes have been among the best teams in the world.

But when it came to the big moments, they bottled the Premier League title race last season. Against Porto in the first leg, on their return to the UCL knockouts after ages, Mikel Arteta and his men struggled and lost 1-0. Anything but a win today will be catastrophic.
