Henry: Arsenal's mistake in letting go of Emery too soon - Paul Vegas

Emery is basking in the glory today following Villa's stunning upset victory over Bayern Munich in the Champions League.

Henry told CBS Sport: "He is a tactical genius. He always goes out and makes sure his team has an advantage tactically because that's how he works.

"We all know what he did in Spain (won the Europa League four times with Sevilla and Villarreal).

"There is no lack of respect for what Mikel Arteta is doing and he is doing extremely well for Arsenal, but I just thought that if we kept him a little longer he would have been successful at Arsenal.

"He showed it immediately after he left the club. I have enormous respect for him."
