Former Germany manager Joachim Low has suggested his biggest disappointed in his tenure as far as working with players.
As was announced before the 2020 Euro, Low is leaving the post to be replaced by former Bayern Munich coach Hansi Flick.
After the ultimate success of winning the 2014 FIFA World Cup in Brazil, Low was asked to identify one of the outstanding setbacks of his time with the European giants.
"Mesut leaving the national team without consulting me beforehand was a great human disappointment for me," Low said as quoted by Goal.
"The time will come when we will talk or meet again. At some point, the day will come when we will talk things out and put everything aside.
"These memories will then also be positive for us. He was an incredibly important and great player with great skills," Low concluded.
Meanwhile, the biggest 2020 Euros game so far will be Italy taking on Spain in the semi-finals this week.
