Arsenal legend Charlie Nicholas thinks that Arsene Wenger has a great squad at his disposal this season.

A number of fringe players such as Lucas Perez, Kieran Gibbs, Rob Holding and Aaron Ramsey performed admirably for the Gunners in the 4-1 Champions League win over FC Basel on Tuesday.

Nicholas believes that there is a competitive edge in the Arsenal squad and Wenger has a fabulous selection headache on his hands.

"Arsenal have got their swagger back and were in the groove," he said on Sky Sports.

"He didn't score tonight but Alexis Sanchez, alongside Mesut Ozil, was absolutely fabulous to watch.

"The players that came in also did well. Lucas Perez got a hat-trick, Alex Iwobi scored, Kieran Gibbs basically got three assists and Rob Holding also played well at the back. So it's all good news and a happy December so far."

"The squad's so strong. You've got Walcott on the bench, you've got Alex Oxlade-Chamberlain, who has been getting the nod ahead of the likes of Iwobi, who also grabbed a goal. Now Wenger's got a fabulous headache.

"It's amazing what a competitive edge does to a group because you don't need to be the best of mates, but in training, you'll feel the spirit, you'll feel the togetherness and you'll feel the endeavour that you've got to be at the top of your game to impress the manager."
