Been reading a few things on his days at Monaco and the stubborn pattern we see here didn't develop overnight. He was there for 7 years and won a league title and cup on his early years. Lost a Cup Winners Cup final, a string of Quarter and Semi final exits in Europe and a consistent record of finishing on the top 3. Finally got the sack when he finished 9th. Was a hero at first but fans grew tired of the lack of progression from what I've read. Trying to find out more.
His philosophy of keeping a team together and the youth set up comes from his love for Ajax and the Total Football years. He's trying to achieve the same at Arsenal but keeps hitting a brick wall. 7 year at Monaco and 1 league cup, 1 title isn't a great record. He won the title in his first season and after that it went down hill. I don't think he has it in him to get Arsenal out of this rut. His trend is to dig his heels in until sacked.
