CHARLIE NICOLAS says he cannot believe Nicolas Pepe escaped being hauled off for his poor performance against Watford.
Arsenal's £72million record signing failed to sparkle at Vicarage Road as the Hornets came from two goals down to force a 2-2 draw.
And club legend Nicholas says he is amazed the Ivory Coast star was not substituted - as manager Emery sacrificed Mesut Ozil and Dani Ceballos instead.
"How Emery took Mesut Ozil and Dani Ceballos off ahead of him was beyond me."
Pepe is slower than Arsenal hoped to make an impact in the Premier League following his move from Lille.
The 24-year-old has yet to hit the target for the North London club - including a shocking miss when clean through against Liverpool with the match still in the balance.
But Sky pundit Nicholas believes the biggest issue for his old club ahead of their Europa League clash with Eintracht Frankfurt is sorting out the defence.
He added: "God only knows what defence Unai Emery will pick. I don't know how often we will have to say it as Arsenal fans.
"It is scary how bad Arsenal are defensively.
"What is the attraction to Sokratis Papastathopoulos? I would play Kieran Tierney on Thursday and see if Hector Bellerin could start too.
"Konstantinos Mavropanos is still game time away from being fit. It would be the end if Shkodran Mustafi was to be brought back.
"We need to get Rob Holding, Bellerin and Tierney back into the side as soon as possible. I would take a hit and play these players to give them game time and let them get match fitness.

"It is starting to effect Ainsley Maitland-Niles and some of the other young players. Reiss Nelson and Joe Willock came on and could not keep the ball.
"It is the manager's responsibility. He must resolve this and come to a conclusion on how to sort this out.
"Tierney, Bellerin, and Holding should play - I would play them this week and take a defeat if it meant they got the game time they needed."
