Arsenal claimed one of their biggest wins of the Premier League this season away at West Ham, with Leandro Trossard one of the stars of the show.
The Belgian international was named as the leading forward by Mikel Arteta in the starting XI, and Trossard hugely repaid the favour by scoring arguably the goal of the match.
Yet it was in the 32nd minute that Arteta showed his appreciation for Trossard, with Sky Sports commentator Nick Wright spotting what the Arsenal manager did to the winger.
Mikel Arteta high-fives Leandro Trossard as Arsenal trounce West Ham

It was a match of celebration for Arsenal as the Gunners blew West Ham out of the water with an incredible first half, prompting what felt like half the home crowd leaving at the break.
And at the hear of the action was Trossard, who again showed why at £20m he has been one of Arsenal’s best bargain signings in recent years.
Indeed, the Belgian international was at his brilliant best today, and Arteta was seemingly pleased with the attacker after giving the forward a high-five on the pitch.
Wright said on the commentary: “Beautiful diagonal pass from Trossard to release Martinelli there. He then gets a cheeky high-five from Arteta following a tackle next to the Arsenal manager’s technical area.”
Gabriel Jesus could struggle to replace Leandro Trossard up-front

The last two Premier League games for Arsenal have shown their tactical flexibility, with Kai Havertz thriving up top against Liverpool as Trossard led the line expertly today in east London.
All of this has happened in the background of Gabriel Jesus being out injured, with the Brazilian international not even making the bench this afternoon to face West Ham.
And with the striker close to returning, Arteta has a big decision to make surrounding who will lead the line for Arsenal, with Havertz and Trossard both fine options for the Gunners.
Indeed, the north London side have hit their best form all season after their dominating win against West Ham this weekend, and Arteta has a huge call to make in the coming days over who should lead the line.
