Everton manager Roberto Martinez is not getting carried away by his side's strong start to the season and insists they are still not at the peak of their powers.
Second-half goals from the ever-impressive Romelu Lukaku and substitute Leon Osman handed the travelling Toffees a 2-0 win at Aston Villa on Saturday, with Tim Howard's excellence between the posts also a decisive factor.
The result left Martinez's men with 15 points from the last 18 available to them and kept them in touching distance of the Premier League front-runners.
In previous seasons, Everton might already have been talked about as potential Champions League gatecrashers but, with the field seemingly more crowded than ever, the Spaniard was content to play down talk of a top-four challenge.
"We're in October. It would be stupid of me to say that," the former Wigan boss said.
"I don't think this was us at our best. If we were our best and the league finished tomorrow, we'd have a great chance, but there are many things we need to do better, many things to improve.
"All we want now is to get as many points as we can while we're developing and we can use the competition for places here to become as good as we can.
"The nature of the competition is to get as many points as we can, then, in March or April, we can reassess the situation and see where we can fit in to the league at the end of the season."
On-loan Chelsea striker Lukaku was the understandable centre of attention on Saturday, having outperformed his fellow Belgian Christian Benteke and registered his fifth Premier League goal in as many matches for Everton.
But Martinez was also effusive in his praise for Howard.
Had he not made a stunning penalty save from Benteke in the seventh minute, Villa may have been home and dry by half-time.
"I thought it was a very important clean sheet and nobody deserved it more than Tim Howard," Martinez said.
