Arsenal struggled at home to Tottenham as they had to fight back for a draw, with the away side winning the battle in midfield.
Former Gunner Martin Keown singled out Joel Campbell as an under performer, arguing he was a poor fit for the tactical contest.
He lamented the injury enforced absence of Aaron Ramsey, suggesting that Tottenham were able to exploit his ineffectiveness.
He told The Mail: "In years gone by, Arsenal have often used an energetic player out wide — such as Ray Parlour — to bolster the midfield and enable them to dominate.
"But Joel Campbell isn’t that sort of player, and with him filling in for Ramsey on the right-hand side Arsenal were unable to outnumber Tottenham in the build up to their attacking moves. For the most part, Tottenham snuffed them out with ease."
Arsenal substituted the Costa Rica international in the second half, bringing on Kieran Gibbs in his place.
Gibbs' normal position is at left-back, but in midfield he was able to score the important goal, while also giving focus to his defensive duties.
The Gunners looked a lot better after making the change, and it's fair to wonder looking back if Arsene Wenger wishes he went this way from the very start.
Campbell has made good progress over the past month, getting four consecutive starts due to injuries in the Arsenal squad, and even scoring his first ever goal for the club a week ago against Swansea City, but this will be a match he will not look back on as fondly.
