Manchester United boss Ralf Rangnick is sorry to have lost Kieran McKenna.
The former United coach was named Ipswich Town manager last week.
The Athletic says McKenna made a 'strong impression' on Rangnick during their brief few weeks working together.
The German took over from Ole Gunnar Solskjaer earlier this month and, so far, has won two of his first three matches in the role.
McKenna was said to have been 'more than capable of delivering string coaching and development messages', while also driving 'technological advances'.
It's stated many players will now miss McKenna and feel he didn't deserve the criticism that went his way.
