Kostas Manolas joined Roma from Olympiakos in 2014. Manchester City, Manchester United and Chelsea are all interested in Roma defender Kosta Manolas, the player's agent has said. Manolas, 25, has been linked with a move to City this summer as Pep Guardiola looks to add to his defensive options. Speaking to Italian newspaper Il Tempo, Ioannis Evangelopoulos refused to comment on whether the Greece international would stay in Serie A, but confirmed Manolas is in demand. "The best clubs in Europe want him," he said.
