Carlos Sainz has aimed an unusual criticism at F1 sprint weekends, as confusion around the format of the events going forward continues.
The Ferrari star believes there's 'definitely something fishy' going on with the current format, criticising sprint races for robbing some of the excitement of the main race.
The Spaniard did, however, struggle near the end of the season with sprint events such as Qatar and Brazil providing the Ferrari man with some difficulty.
F1 have confirmed that sprint race formats will change ahead of the new season, but what that may look like is still unknown.
