Manchester City manager Pep Guardiola was unhappy with Everton defender Yerry Mina for what he implied were underhand and unsporting tactics during their 3-0 win at Goodison Park.
The Colombia international was involved in one visible incident with Aymeric Laporte at a corner in the first half in which the City centre-back slapped his opponent in the stomach following an altercation and Mina fell to the floor.
But at the final whistle Guardiola confronted the Everton defender and remonstrated with him as he followed him off the pitch. All City's players also refused to shake Mina's hand.
