The Gunners second half display was as bad as anything we’ve seen in recent years, and the German admitted that players were ‘crazy’ in the dressing room afterwards.
However, he also seemed to take a little pop at the tactical approach/in-game management following the 2-2 draw at Vicarage Road.
“The distances between all parts of the team were too big so they had so much space, especially in the second half,” he said.
“It was too easy for them and they could go around our box. I don’t know why it was like that but everybody could see that we have to talk about this.
“In the first half it was better but not perfect. I think we have to be honest and analyse this game.
“We were lucky we didn’t lose.”
The 27 year old admitted passions ran high afterwards, but said Unai Emery remained positive, looking ahead to the next game against Eintracht Frankfurt on Thursday.
“Everybody was angry and disappointed after,” he continued. “Everybody was emotional, very mad and crazy. But that is normal.
“The manager is a very positive guy. He said ‘Calm down and then on Tuesday we analyse this game and then on Thursday we have another game’.”
