Former Celtic flop Efrain Juarez has quit his job at Colombian double winners Atletico Nacional in protest over their transfer dealings, as they stall signing ex-Rangers striker Alfredo Morelos.
The Mexican coach walked out on the Medellín side after becoming frustrated with their transfer policy.
And Juarez had also reportedly become unhappy at the club's progress in trying to turn Morelos' loan from Brazilian club Santos into a permanent transfer.
Morelos helped Atletico Nacional to a league and cup double and rediscovered his scoring touch by netting seven goals in 18 starts.
But talks have stalled with Santos - who appointed former Ibrox boss Pedro Caixinha as their new manager last month.

Juarez overcame a remarkable three-year ban from Colombian authorities after he was hammered for 'excessive celebrating' in a derby Cup win over Independiente Medellin. He appealed the ban and won his case.
But reports in Colombia indicated he was unhappy at the delay in signing Morelos and also with the arrival of Ecuadorian full-back Billy Arce without his knowledge and the sale of two players - Pablo Ceppelini and Alvaro Angulo.
