Belgium's players will have undoubtedly been very excited about the prospect of being coached by Thierry Henry - and understandably so.
The Arsenal legend was confirmed as Roberto Martinez's assistant on August 26, giving the likes of Romelu Lukaku, Eden Hazard and Michy Batshuayi the chance to learn from one of football's greatest ever finishers.
So, how might Henry use his experience to train the Belgium national side?

Visual demonstrations perhaps? Trial and error? Well, according to Lukaku, the Frenchman has been giving coaching tips in a very unique - but bizarre - way.
Believe it or not, Henry has been giving advice to his players using a Playstation - and FIFA, you would assume.
Lukaku said, per the Mirror: "He is really with us and not at all distant. Sometimes he comes to drink a cup of tea or play Playstation with us.
"With [Christian] Benteke and Hazard, he took us aside. He corrected my way of escaping a marker.
"We spent a long time in front of the screen and he pointed out our mistakes and told us how to do it. We listened really carefully. It took about two hours but it was great."
Speaking to Derniere Heure, Lukaku also revealed how he addresses his new assistant manager as 'Monsieur Henry'.
"It is a mark of respect," the Everton striker added. "I also used to say Monsieur to (Samuel) Eto'o and (Didier) Drogba."
By the sounds of it, Henry has made a very good impression in the Belgium camp.
"He asks a lot of us but we need it. He is a very good communicator and makes himself heard. It is all based on concentration and effort.
"To have him with us is a plus. I can assure you that we listen when we speak.”
Henry's presence couldn't prevent Belgium from falling to a 2-0 defeat against Spain last Thursday, with David Silva the scorer of both goals.
