He is not ready to manage a big club yet. Sure, he achieved great things at Porto but being brought out of his comfort zone has definitely exposed his shortcomings. The poor man-management skills, the tactical stubbornness, the clueless way he handles the media and supporters
Highly doubt he will get another job in the EPL again. He will probably have to go abroad to rebuild his reputation. The likes of PSG and Madrid which once courted him, probably for the image he projects of a young, stylish and successful manager, will definitely not take a chance on him. Italy will be his next destination I guess
