Alonso is preparing for his home race at Barcelona's Circuit de Catalunya off the back of his debut win at last week's World Endurance Championship race at Spa-Francorchamps, Belgium.
"We had the plan beforehand which was overtaking cars at the start because we started on the supersofts so we knew we had to stop quite early", he said.
"It was a good qualy, so I'm very happy, without a doubt", said Alonso.
McLaren has never hidden the fact that its aim for 2018 was to top the midfield and close the gap on the top three teams. He's going to wait and see how these developments come along - we have more developments coming - so in the middle of the year we will sit down and make a decision. "That's what we wanted today and I am happy right now".
"Every Spanish Grand Prix is special, and there are always a lot of emotions when you go out there and feel all the support".
"At least the positive note is that everything we brought for the vehicle works as expected". "I thought maybe some rain could have helped us, but unfortunately it didn't come in the end".More news: Starbucks Restrooms Are Now Open to All
"We did a good step here". We've had good race pace and we need to fight to get ourselves in a good position in order to benefit from other people's mistakes.
"We can put on paper now what would be the qualifying result here on Saturday, what it would be in Monaco, in Silverstone".
Alonso praised his team for the step forward they made with an upgraded package of new parts. However, while not yet a cause for celebration, eighth and 11th positions on an aerodynamically-challenging track such as this mark our best qualifying session of the season so far, and is certainly the step forward we were hoping for on track to correlate with the evidence we saw in simulation.
"But luckily we had a good race, we keep scoring points, five consecutive races in the points".
The highlight of the Spaniard's race was a bold around-the-outside pass on Esteban Ocon at Turn Three after the Safety Car, although Alonso added: "We are still lacking some straight-line speed to be able to overtake".
