Thierry Henry explains huge Arsenal difference Mikel Arteta has never had before

Thierry Henry has insisted that Arsenal's impressive squad depth available to Mikel Arteta gives them a huge chance at success this season. The Gunners extended their impressive start to the campaign on Wednesday with a 2-0 win over Olympiacos in the Champions League.

Gabriel Martinelli repaid Arteta's faith with the opening goal after Viktor Gyokeres' effort hit the post. The Gunners dominated the Greek giants throughout before Bukayo Saka scored his second goal of the season in injury time.

The victory leaves Arsenal fifth in the Champions League league phase on six points alongside Bayern Munich, Real Madrid, Paris Saint-Germain, Inter Milan and Qarabag FK. So far this season, Arteta's men have won seven of their opening nine games in all competitions.

After two seasons of falling short on all fronts due to the size of their squad, the north Londoners significantly improved Arteta's options in the summer transfer window. Eight new players came in for a total of £257million, with the likes of Gyokeres, Eberechi Eze, Martin Zubimendi and Noni Madueke all bolstering positions.

The business completed by new sporting director Andrea Berta has put the Gunners in a good position to succeed this season. Many have predicted that they will end their wait for a Premier League title, while also going all the way in the Champions League, which is also a possibility after losing in the semi-finals last season.

Speaking on CBS Sports' Golazo show alongside Jamie Carragher and Micah Richards, Henry dropped a hint on his prediction for his former club when discussing the importance of having a good squad to choose from. When talking about Goncalo Ramos' impact off the bench for Paris Saint-Germain after his winner at Barcelona, he said: "I do believe that you go through a season, you need your bench.

"This is why I think Arsenal, this year, have a big chance to win stuff because the bench can change the game."

So far this season, Arsenal have had 11 goals provided from players off the bench - all coming in the last five games. Leandro Trossard and Martinelli have both scored twice and assisted one, while Saka and Martin Odegaard came off the bench for the second goal last night.

Asked about the reassurance he has when he turns to his bench, Arteta admitted it makes a difference. "With all respect, last season we were looking and we had five academy players there that probably never played professional football in the Champions League," he said.

"It makes a difference. Today we decided to change six players, I think it was, because I want everybody to really be involved and feel part of it, and it was great.

"We had the feeling as well that physically we were dropping because we played a really intense match in Newcastle a few days ago. The ones that come in again, they lift the level, they help us win the game, and that's great."
