Theo Walcott scores two and Arsenal fans don’t know what to do

Theo Walcott is surely the most frustrating player in the Premier League.

He's got great pace, has been coached by one of the world's greatest managers and plays alongside some of the best players in the game. Yet for 10 years now he has never quite become the player he should have. Sometimes he's out on the wing, sometimes he plays through the middle - but it never really seems to click on a long-term basis for him. Until tonight. He headed - yes, headed! - Arsenal in front against Basel early in the first half at the Emirates. Then a few minutes later, he did this: https://twitter.com/btsportfootball/status/781211581979955200 That makes it five goals in seven appearances for the England man - and Arsenal fans, faced with the prospect of him actually producing the goods on a football field in a competitive fixture, really aren't quite sure how to handle it. Some have gone down this route... Sure you did, fella: https://twitter.com/muhdrills/status/781214822490841088 Uh huh: https://twitter.com/BendifsBants/status/781214791314604034 But not everyone saw this coming: https://twitter.com/bae_llerin/status/781214783710302208 Some are instant converts: https://twitter.com/sashamaisarah_/status/781212848739332097 And some are just relieved: https://twitter.com/keonbecky/status/781210075889176577 Others aren't quite convinced it's really him: https://twitter.com/SarbajitDas14/status/781212866732896256 https://twitter.com/seanbaker87/status/781211427021393920 https://twitter.com/FutbolsaCountry/status/781210734747328512 While some are 'doing a Donald Trump' and removing certain tweets they sent about him: https://twitter.com/santasbaIlsack/status/781205729449500672 And others? Well, they called it: https://twitter.com/VivaLaGiroud/status/781212857778266113
