Southampton boss Ronald Koeman admits he doesn't see eye-to-eye with Manchester United manager Louis van Gaal.
The two men will meet for the first time in the Premier League on December 6 at St Mary's, having enjoyed a rocky relationship since they first teamed up in the late 90s, when Koeman was Van Gaal's assistant at Barcelona.
"We had a problem because I was the coach of Ajax and he [Van Gaal] came in as technical director," Koeman openly admitted to The Independent.
"We had some problems in the relation between his job and my job. First he left Ajax and, after three and a half years I left, too. It was difficult because it was a problem in the relation in football.
"But you know, if there is a problem in football relations then there is also a problem outside of football. Never more was there the contact that we had before. Sometimes a little bit fighting [dispute] between each other.
"Yeah, that's true [that Van Gaal said that],' Koeman said, when asked about Van Gaal's describing him as 'weak'. 'But that is his story. My story is different. If there is a fight with two persons, both are involved in the problem. It's OK. It is the past and we look forward. I hope he will be very successful."
