Timo Glock declared himself pleased with the progress made by the Marussia team on the final day of the three-day F1 test at Mugello.

Although towards the bottom of the times, the German was able to complete more than 100 laps at the wheel of the MR01 in a busy programme working on tyre compounds and evaluation of aerodynamic upgrades that are set to be introduced in Spain next weekend.

Having endured a troubled day on track on Wednesday, Glock said he was pleased to finish the test on a high as the team now hopes to build on the testing performance when the European leg of the season starts in Barcelona.

"A pretty good day I have to say," he said. "We got a lot of laps - 110 - and worked our way through many different things with the car. We were able to do a lot of comparisons and a lot of set-up work also, so in the end, I think it was a good last day and we have some important data to look through for Barcelona. Now we focus on the implementation for the Spanish Grand Prix and with some new components see what we can do there to continue the progress."

Team principal John Booth admitted the week had been a challenging one for his team but said he was hopeful that the end result was a forward step towards the rest of the field.

"It has been a challenging week for the team as we have been working to a not insubstantial programme of tyre evaluation, set-up work and the proving of our new aerodynamic package for the start of the European season," he said. "At the same time as working through these items we have been making directional calls in each area, based on our findings, and effecting production back at base to ensure we have the parts ready for next weekend's race, all in pretty rapid succession. So it has been a real 'team' effort and I'd like to congratulate everyone on a job very well done.

"It's fair to say we feel we have made good progress this week with our package, but we are quite certain that our competitors will have been busy too! For that reason I'm not going to make any predictions beyond saying that if closing the gap was our target, this week's results would suggest that we have made another positive step forward."
