Txiki is part of the City triumvirate, including Soriano & Pep. Those three are the real secret behind our success, albeit Berrada was a crucial part of their team.
Shit happens & employees move to rivals usually for far more money, and/or a higher position. It's happened to my company which severely pissed us off.
However, it made us tighter & even more determined to succeed, especially over the competing companies.
Let's just hope this gives us fresh impetus to drive forward & prove that City isn't a one man band, but a complex mechanism of interchangeable high quality parts, which when combined made us Treble winners & World Champions.
If those three are the holy trinity then Omar is the pope.
He was the person who Barcelona got very upset about us taking, which makes sense because he tripled their commercial revenue in 5 years in the early 00s.
No point in downplaying this, having your COO get poached by your main competitor is going to be a headache on all sorts of levels.
