The former Manchester United, Chelsea and Real Madrid coach gave a dismal verdict after his team finished their campaign with a 2-1 win against Konyaspor on Saturday.
He told reporters: "We finished second in the league, that wasn’t our goal. We actually had a good season until we lost the title. It was difficult to get the team back on track. Strange things happened in the league and also against Rangers. I can’t describe it. Overall, it was a disappointing season. When a new coach arrives, people get hope. If we compare this to the phase when there was no chance of winning the championship, people lose motivation, the stadium is empty and there are reactions.
"I don’t blame my players, they are human and professional. They are the first to feel sad about the bad results. I am not happy."
