Arsenal boss Arsene Wenger was left in a state of shock after a rogue fan stormed down the touchline and approached the bench during the 2-0 defeat against Southampton.
It was the last thing the Frenchman needed during a poor showing at St. Mary's, as two defensive mistakes cost the Gunners any chance of picking up the points on the south coast.
Wenger appeared to get his tactics wrong on the day, with Alexis Sanchez initially leading the line before Theo Walcott's introduction. Defender Calum Chambers also played in midfield.
Whilst the Arsenal boss has had his hand forced on a number of occasions, he continues to show little faith in the likes of Joel Campbell, who could have got the nod up-front, thus allowing Sanchez to create behind the striker.
A section of the supporters at the Emirates Stadium have been against Wenger for some time now, and a banner calling for the manager's head was unveiled as recently as November during the win at West Brom.
Whether he can turn it around with that certain section of supporters remains to be seen, but a big signing in the January transfer window certainly wouldn't help. Given the calamitous nature of the conceded goals on New Year's Day, a defender or goalkeeper might be the best option.
Wojciech Szczesny was at fault in some capacity for both goals, wrongly coming out for the first and then gifting the second to an opponent. Per Mertesacker continues to look one-paced at the heart of defence.
A number of big names have already been linked with the Gunners, but it remains to be seen if Wenger can force a move through when the window opens on Saturday.
