Poch did not walk out on us we dumped him. I think it is petty and small minded to dump someone and then whinge like a little bitch because they then move on to our rivals even though they had been waiting around, hoping we would come back to them and give them a second chance.
I'm not sure who you were replying to, but for what it's worth - Poch took us as far as he could, at the time we were in as a club. Before Ange was appointed I was firmly in the Poch #2 camp, but honestly I see now that our paths have split, likely for good.
Whether it's the right or wrong thing to do, managing Chelsea or Arsenal turns a part of the fan base against him. This means were he to come back, the first thing we would see would be a section of the base turning on him the moment something wasn't perfect.
Poch was as important to the development of this club as Martin Jol, and was treated just the same - but unless something changes soon, he is going to be a "not quite" manager.
