Former Arsenal striker Niall Quinn isn't convinced about their trophy chances.
Quinn doesn't believe they have enough class.
He told the Sunday World: "Sanchez is a great signing and the same goes for Welbeck, but are they ready to challenge for the Premier League title or the Champions League?
"I have to be honest and say that if I was pushed into a corner and asked to pick a Premier League winner and a Champions League winner, Arsenal would not be a name I would come up with.
"What they do have this season is a variety in their attack that was lacking up to this point. So much pressure was thrown onto Olivier Giroud's shoulders to carry the Arsenal forward line last season and to his credit, he handled that quite well.
"Now Wenger has Welbeck to offer a different type of attacking threat with his pace. He has Sanchez to throw in that little bit of magic and he will have Giroud back later in the season to play as the lead front man if required. Arsenal have a variety of options now and that is vital to any manager."
