The former PSG manager has confirmed that they had been working in training on Welbeck filling in at that role: "Danny Welbeck is one of the players who has a multi-position possibility", Emery said.
Emery is convinced the Gabon global can win the Premier League's Golden Boot this season.
Arsenal supporters had been in excited mood ahead of Unai Emery's first Premier League game in charge, but for all the optimism which preceded it, the new era began with a defeat which showed the size of the task facing the new head coach. "At times it has cost them with the ball going wide, but that's the reason why Emery wanted so many players in the centre".
I was surprised to see Petr Cech starting this match, as I thought new signing Bernd Leno would get the nod.

Grigor Dimitrov will face Anderson next after finding some of his best serving to beat Frances Tiafoe 7-6 (7/1) 3-6 7-6 (7/4). The 21-year-old German moved ahead early in the second set but Tsitsipas broke at 3-5 and held serve to pull event.
Cech made several saves to keep Arsenal in the game but also seemed to struggle a bit when playing with his feet, almost scoring an own goal in the first half when he mishit a back pass from Guendouzi. Danilo is expected to miss the opening games of the season with an ankle injury.
"I said to him when he [Welbeck] arrived with us after the holidays, I want the best performance in his career from this player - and to work for that", he said. And we count on him. And it felt like they seamlessly continued that form as they comfortably defeated an Arsenal side looking slightly disjointed in their first competitive match under Unai Emery. The fact that he is the Man of the Match says more about others than it does Cech, in all honesty.
The fans are definitely much more confident for the start of the new campaign and perhaps Emery has given the same boost to the players.
"When we are thinking in an attacking moment, I want the goalkeeper thinking for that, he is the first".
Guardiola took time to settle too, but he answered his critics last season and his team's performance in the Community Shield suggested that they are raring to go once more. And the team for 90 minutes, they ran, they tried, they pushed, but I think we need to improve [everything], collectively and also individually.
