Toto Wolff reiterates Mercedes must "sort out" their problems ahead of Belgian GP

Mercedes team principal Toto Wolff has admitted the Silver Arrows must "sort out" their ongoing problems in order to have a chance of winning the 2019 Belgian Grand Prix this weekend.

The reigning world champions have dominated most of this season's championship and has a commanding lead in the constructors' standings for proof of their dominance.

Max Verstappen has won in Austria and then Germany, but apart from those two races, Mercedes have won every single race in 2019, with Lewis Hamilton on his way to a sixth world title.

However, the Silver Arrows have struggled to control their engine temperature, with this apparent in Austria, where they had a shocking race by their standards, and this is something Wolff has addressed and admits it needs to be sorted out ahead of the weekend.

"After the break, getting into Spa and Monza mode, they are totally different track layouts, very power-sensitive circuit - something that's going to suit Ferrari a lot," the Mercedes boss said, as cited by Crash.net.
