The likelihood is announcement due tomorrow or Friday.
Although various posters have referenced the 1/7/13 starting date, it has no effect which prevents the Manager/Coach from being involved in taking/making decisions prior to the said registered starting date. As has been mentioned elsewhere on this thread, he will have made his contributions to the discussions about transfer targets and possible moves away.
As is already known, Mourinho and Moyes have been installed. Both have been active regards the planning of the new season having held extensive discussions with club officials and directors. Both of these will be taking a holiday until the end of June and meeting up with the squads when training recommences on 3/7/13. Gollum will need to speak with Shrek and others, Mourinho with Lukaku and others before then.
In the meantime, here is the Wikipedia entry on Señor Pellegrini which makes interesting reading.
