Toto Wolff, Head of Mercedes-Benz Motorsport: Clearly, Barcelona was tough to take. We came away upset at an opportunity missed - but this is racing. The drivers know how we operate. The team is responsible for giving them the best possible cars and they are responsible for getting the best out of them - and for bringing them home. When we let them down, we apologise to and the same goes the other way. It's a pretty normal culture - we deal with setbacks together and we move on. Now, we go to Monaco and a very different challenge. Once again, we have seen our competitors make steps forward which have given us an even bigger battle on our hands. Red Bull came out on top in Barcelona after a close fight with Ferrari, so it's clear that we are under attack from more than one angle. We cannot afford to drop the ball, so we must remain united, remain strong and hit back hard this weekend.
