Former Atletico Madrid coach Radomir Antic has spoken of working with Real Madrid boss Santiago Solari.
Solari played for Antic at Atletico.
Asked if Solari is similar to Atleti coach Diego Simeone, Antic told AS: "I don't like making comparisons. It wouldn't be fair to compare them now, with Solari only just starting out in coaching and Simeone with a proven track record."
And on advice for his former midfielder, Antic added: "Just to be aware that being Real Madrid coach demands delivering the maximum performance in every training session and every game."
