A history of training ground bust-ups between teammates

The row between Sergio Ramos and Sergio Reguilon during Real Madrid's training on Monday was just one of the many that have occurred over the years between teammates.
Some of these cooled down relatively quickly, but others led to the intervention of other colleagues to relieve the tension.
