Toto looks ahead to Round 5 of the 2019 Formula One season in Barcelona...
It's been a remarkable start to the season for the team, but we know our points tally isn't a true reflection of the current competitive picture.
"Nobody would have predicted four consecutive Mercedes 1-2s after winter testing," said Toto. "But here we are having scored 173 points in the first four races - a remarkable result which is first and foremost testament of the amazing work of every single member of the team.
"Our devotion to the task, our hunger for victory and our love of racing are stronger than ever.
"The results seem to paint a relatively clear picture, but the truth is that they're too flattering. The performance has fluctuated in the first four races.
"We had the fastest car in Australia and China, but we won in Bahrain thanks to our reliability when we were on the back foot in terms of speed. And while our race pace looked good in Azerbaijan, we were never able to build a truly comfortable gap to our rivals.
"So, there is no complacency about our situation because we know that it's not truly representative of the balance of power this season so far."
The Circuit de Barcelona-Catalunya is a venue that all teams know well, following on from the two pre-season tests there.
Our rivals showed impressive pace at the track over the winter and we suffered some challenges there, so we're not expecting an easy weekend.
"Our next stop takes us to Barcelona, where our opponents were blisteringly quick in winter testing, so the Spanish Grand Prix will be anything but easy," Toto explained.
"Despite the good start to the season we remain quite sceptical of our own performance and know that there are a number of areas where we can and must improve.
"We anticipate a tough and competitive weekend, first against our rivals and also between our drivers. Everything is still very much up for grabs this season and we will be keeping our foot firmly to the floor."
