Cesc Fabregas has warned the rest of the Premiership that Arsenal are only going to get stronger.
The Gunners lost 2-1 to Chelsea in a dramatic Carling Cup final on Sunday but their young players again caught the eye.
Theo Walcott scored his first goal for the club to put Arsenal ahead, while the likes of Abou Diaby, Denilson and Armand Traore impressed throughout the entire Carling Cup campaign.
Fabregas believes Arsenal could be the dominant force in English football within three years and thinks the competition should be very concerned.
"If I was in another team, I would be scared if you could see all the young players who are coming from this Arsenal team," said the Spaniard.
"You can see that if we keep playing for three more years together, then we could do something really big for the club.
"We have shown great talent here. I am also young and just try to do my best for the team."
Fabregas felt Chelsea had luck on their side in the first half at Cardiff, as they withstood Arsenal's pressure and went in level thanks to a controversial equaliser from Didier Drogba.
"In the first half we should have been 3-0 up. Manuel Almunia was doing nothing in the goal," said Fabregas.
"In the second half, Chelsea tried to push a little bit more, and credit to them because they are a good team.
"However, their first goal was clearly offside."
