opponents Chelsea are a 'very complete team' who
have improved their attacking options over the
summer.
The Toffees have been in front in both of their
games so far this season but have drawn both 2-2 -
against Leicester City and Arsenal.
Martinez admits those setbacks have hurt him and
accepts that his players will have to be at their
absolute best to take anything from the game
against Jose Mourinho's Premier League title
favourites.
Martinez said: "We know it is going to be a difficult
test, but we feel hurt about the points we have
dropped so late and everything is down to us to try
to be as good as we can," he said.
"But unless you are at your top level you can't really
compete against teams like Chelsea.
"It is clear Chelsea and Manchester City have started
really strongly. They have shown they have no
stopping period, they have just started where they
left off.
"They are looking in top form straight away and it
could be a really difficult sign for everyone else.
"We know how they played last season and now
they have got more flair and more options in attack.
That makes them a very complete team."
Martinez led Everton to fifth last season and is
confident they can be a top side again this time
around.
The Spaniard has been encouraged by some of his
team's play in their two games to date but is aware
they need to maintain their good periods for longer.
Martinez said: "It has been very curious (so far). We
have shown incredible signs of the team that we can
be.
"We need to extend the first 45-minute performance
for 90 minutes.
"When we do that I think we are going to see the
potential of the squad."
