Aston Villa midfielder Nigel Reo-Coker says Martin O'Neill's team is nowhere near peaking.
He told Villa's website: "I always want to do better. It's important to always want to learn things and do more. That's what we all have to realize. "Life's about achieving and I've always felt like that. I'm not scared of anybody in the Premier League. I just want to go out there and be the best I can."
"The thing we need to really cut out is making individual errors that have been costing us. It hasn't been that we haven't got good enough players or that we've been outplayed, it's our own errors that have cost us games.
"That more frustrating to us as players than anything else. It's a lot more frustrating to us than it is to the fans because we know what we're capable of. We work hard on the training ground and it's about learning to eradicate these errors.
"If we look back through the course of the season at the games we should have won and the points we should have had, it's frustrating.
"There's a great opportunity to achieve something here. What we've done this season with the squad we've had is a fantastic achievement."
