The Greece midfielder Giannis Maniatis was so enraged after a training ground spat that he booked a himself on a flight back to Athens before being persuaded not to walk out on Fernando Santos’s squad.

The versatile midfielder was so infuriated by the standard of crosses delivered by Giorgos Tzavellas in a training exercise that he confronted his team-mate and capped a heated exchange with: “What are you on about? This is not Paok.” The players then had to be separated.
