A few points to consider
1) In as much i would love to see Tito back in a few weeks, it doesn't look likely based on the information circulating. The last time he had this scare it was operated on and he was ok. Today, we have learnt that he will be operated on and then do chemo. That's different. I've never done chemo but from research, i don't think Tito can handle chemo and the demands of being FCB's coach. This is a 24 hour job.
2) I see a replacement for a period of 3-6 months. i can only see Pep working out as this replacement, because he's the only person that can demand the respect of the players. The players will not respect Luis Enrique after a few poor outings. I love luis enrique. this is a very important decision for Rowsell.
