José Mourinho suffered his first league defeat in his second spell as Chelsea manager but insisted the better team had lost at Everton. "We dominated the whole game and had 21 shots, we risked everything we could," the Chelsea manager said after Steven Naismith's goal secured a 1-0 home victory. "In that sense I think it's fair to say we deserved to win the game. But in another way, the team had 21 shots and some of them easy shots too, but we didn't score.

"We made a mistake in the last minute of the first half where we lost the ball in a strange situation and we conceded a goal. Maybe because of that, we deserved to lose, because if you don't score you can't win."

The Blues manager would not single out striker Samuel Eto'o, who was particularly wasteful on his Chelsea debut following an August move from Anzhi Makhachkala, for criticism. "Of course he needs [matches], but it was not just him," Mourinho added. "I think [André] Schürrle's missed three big chances to score and other players also had chances but I don't like to be critical of players who missed some chances. We are a team and I prefer to analyse the game. We didn't deserve to lose because we were the best team and the team that tried harder to win the game."

Mourinho admits Chelsea are playing a different type of football this time round, not the powerful, direct style he developed when Didier Drogba was still the spearhead. Yet when he made substitutions he simply reshuffled his midfield. Fernando Torres was brought on only for the last 20 minutes and was unable to make a difference, and while Romelu Lukaku – who has been described as the new Drogba – was at the game it was because he has been loaned out to Everton. "We need to put the ball in the net," Mourinho said. "Artistic football is no use without goals."

It was also a first league win as Everton manager for Roberto Martínez, who had been frustrated by goalless draws with West Brom and Cardiff after overseeing an opening-day 2-2 draw at Norwich.

The former Wigan manager accepted praise for his defence's resilient display but insisted he was equally happy with his side's threat going forward.

"It feels really, really good because it was a special game, a special opposition and a very good performance," Martínez said. "We are still going through a transitional period and I think the crowd understands that and as players we understand that.

"But in the manner that we've been able to defend, sensing danger and coping with one-on-ones then I thought it was superb. We always carried a threat and it's not one of those performances where you feel strong defensively but that you don't look like scoring.

"I thought we put a lot of bodies in the box, especially in the first half, even if I thought our build-up play is not as good as it has been. But in the second half we kept our composure and always carried a good threat in attack, and we coped with every adjustment that Chelsea did. That gives me real pride in the performance."
