Do you seriously think that Maurice Malpas would be a good manager for ICT? He was dreadful at Motherwell, and dreadful at Swindon. Sacked by Swindon, and took Motherwell from being a comfortable mid-table SPL side toa very near relegated one. The only success Malpas has ever had was when he was least with Butcher (and vice versa [they seem to be hopeless apart, but together they become good]).
I am also strongly against a former manager coming back and that would include Robertson. He might have been good when he was here, but he hasn't done much good anywhere else. He might see himself as the next manager in waiting but I don't. Have a look at how many managers have done well after returning to a former club. The one that sticks out is Walter Smith, but he has a huge budget and still hasn't had a massive amount of success. Another fairly successful two-time manager I can think of is Steve Bruce at Wigan, though less so success-wise.
When the time comes that Butcher moves on (hopefully taking Malpas with him), I'll come out on here and endorse a candidate who would come to ICT, has had success, play's attractive football, makes good signings on a smaller budget, and has has even received praise from Butcher. I'll make that endorsement of that candidate and hopefull management team when the time comes. For now I believe that it is too early to tell how well Butcher has, and will do.
