McLaren team principal Andrea Stella admitted that Max Verstappen's three-stop strategy at the Spanish Grand Prix had the team worried, having initially believed the four-time Formula 1 champion's approach was "not going to be a problem".
Verstappen made his first stop at the end of the 13th lap, trading his softs for an identical set - given the timing, it was understood by McLaren that the Dutchman would be three-stopping.
