But Souness said Arsenal should have gone long after a warning sign in the first half.
“There are senior players in that defence. As a manager, you hope your bigger players, it doesn’t have to be the oldest ones, work it out that they’re going to concede.
“Why did the big players not say ‘let’s just go long with it for 10 minutes and see where it takes us’, because persisting with it was going to cost them, and they’re lucky it only cost them one.”
Xhaka: We were scared
2:34 Granit Xhaka says Arsenal were scared and everything went wrong in the second half
One of Arsenal’s better players on the day, Granit Xhaka admitted Arsenal were ‘scared’ in the second half, but said playing out from the back was one of several issues, not the sole problem.
“Everything was wrong [in the second half], we didn’t play our game, we were scared, we know they would push us more in the second half but we have to show more character and play, and not be scared. You can’t give a performance like this.
“We train for short goal kicks, of course mistakes are here but it’s not an excuse. Next time we have to do better, we have to analyse and then we’ll see what happens. It wasn’t only this situation that was a problem – it was the whole second half.”
Souness: How can you be scared?!
“They’re saying they were scared – I’ve never been scared in a game of football in my life. I just don’t understand it. In the game plan, Arsenal were allowed to have the ball, Watford dropped off.
“It’s easy to play when no one’s coming after you, in your face. I could’ve played in that Arsenal team in the first half! But the whole thing changes when Watford are let off the lead, you’re confronted with someone who’s going through you, and they didn’t stand up to it.
“Sometimes you have to have one hat on for one type of game, and another hat on for another. Arsenal proved today they can only play one way – they can’t go to war.”
Emery: Long ball wasn’t working
3:50 Unai Emery says Arsenal were punished for their mistakes
Speaking to Sky Sports after the game, Arsenal manager Emery said the long ball from goal kicks would have caused his side to lose the physical battle in midfield, and admits his side must learn from their mistakes.
“Trying the long ball, they are physically stronger than us, and they were winning that ball. We wanted to break the first line and connect with Mesut [Ozil], like we did with the second goal.
“It was two different halves. In the first we controlled the match how we wanted, in the second they pushed for our mistakes, and we did more than we wanted to do. We need to think about how we can improve, how we can do better.
“We can grow up with the mistakes and learn for the future matches. We said at half-time that 2-0 is not enough, and in the second half we needed to do the same work, but knowing they would do more. They did that, and we couldn’t break the lines.
