Louis van Gaal's two-year tenure at Manchester United will not be remembered too fondly by the club's fans, however, it is easy to forget it was the Dutchman who brought Anthony Martial to Old Trafford 12 months ago.
It was quite a gamble to spend nearly £40 million on a 19-year-old but Martial settled straight into the set up at one of the biggest clubs in the world.
The Frenchman was the club's top scorer in all competitions last season and although Van Gaal is no longer in charge, Martial has paid credit to the man who signed him on deadline day last year.

Martial has not been shy in piling on the praise for his old boss and claimed much of his development at the club was down to Van Gaal.
"I had a great relationship with Van Gaal," Martial revealed in an interview with L'Equipe. "He always demanded perfection from me. He has done a lot for me."

It will come as no surprise to hear Jose Mourinho's predecessor was a perfectionist during his stint at the helm.
While his team were playing, Van Gaal preferred to sit in the dugout and make notes instead of encouraging players on the pitch from the technical area.
But Martial did also admit he found certain aspects of the 65-year-old's methods frustrating.
He added: "He always showed me videos together with his assistant, even when I had scored a double. He pointed out the things I had done wrong.
"Sometimes it was annoying because you expected to be shown the things you did well, but I knew it was for my own good."
Young footballers can often get bogged down with the finer details during their first few seasons in the game so it is easy to understand where Martial is coming from.
As it turned out, an FA Cup triumph was not enough to keep Van Gaal in his job and the French international is excited to work with his replacement, Jose Mourinho.
"Mourinho is a great coach," Martial continued. "He has won a lot of titles.
"I do not really know him personally yet, but I know how much he has won.
"I know that Mourinho has worked with great players and he helped them improve and develop."
Martial featured but was uncharacteristically quiet as Mourinho's reign got off to the perfect start on Sunday afternoon with a comfortable 3-1 away victory over Bournemouth. Juan Mata, Wayne Rooney and debutant Zlatan Ibrahimovic found the back of the net.
