If anyone else is interested, I've just read an interesting post on reddit about how the fixtures are generated in La Liga and why teams always play each other in the same order apart from one special team, Valencia.
That's a great deal for Sauber and sorely needed because they've struggled since Perez and Gutierrez left.
Giovinazzi looks a terrible shout given that he crashed yet another Haas this morning in Practice. Charles Leclerc is the hot property for next year and is affiliated with Ferrari so it's much more likely he'll get a seat with Sauber now that Ferrari's other pals Haas have confirmed Grosjean and Magnussen for 2018.
