"Monaco was not an easy weekend for the team," explained Toto.
"On the one hand, winning in Monte Carlo is one of the best things a Formula One team can experience - especially if it is such a tight race with a nail-biting finish.
"On the other hand, the loss of Niki hit us hard. But we think he would have been proud of the performance we delivered in the circumstances.
"The next race takes us to Canada, the only fly-away race within the European season. To a large extent, the challenges of Montreal are opposite to those of Monaco; the Circuit Gilles Villeneuve is a high-speed track with relatively long straights and lots of overtaking possibilities.
