Following their 1-0 win over Newcastle United, Arsenal manager Unai Emery revealed why he failed to start David Luiz, Keiran Tierney, Nicolas Pepe, Gabriel Martinelli, and Dani Ceballos.
Arsenal had an average first half with the only meaningful chance coming from a Pierre Emerick-Aubameyang shot. The Gunners improved in the second half and opened the scoring in the 58th minute after a brilliant cross from Ainsley Maitland-Niles found Aubameyang who chipped the ball over the keeper.
Speaking in a press conference after the win over Newcastle, Emery was asked why none of his new signings started the game, "The circumstances are different. First David Luiz had a pre-season with another team and is ok to play physically but only trained with us completely yesterday. On Friday he only trained for 30 minutes.
"I was thinking of giving Sokratis and Chambers confidence because they were working well. Pepe is different. He is now in pre-season. He came one week ago, physically he needs to get the best paces, to get fit, to be ready to play 100 percent for 90 minutes. Today 20 minutes is good for him.
"[Dani] Ceballos is in the middle. He came before Pepe and he had an injury and stopped training. He needs also to know the Premier League. The first match for him is important for us. That's the reason. I used Reiss Nelson and [Joe] Willock because they deserved to play. With confidence, they can help us. [Gabriel] Martinelli the same."
