Netherlands boss Ronald Koeman received a cheeky request from Manchester City boss Pep Guardiola over the international break.
Guardiola, who is hoping his players stay fit as they go into the season run in after the break concludes, wanted to talk about one of his stars.
He was referencing defender Nathan Ake, who has played a crucial role in the City team this season.
"I got a call from my friend Pep on my birthday this week," Koeman said to reporters.
"Pep wished me happy birthday, but very quickly he also asked me if I could be careful with Nathan Ake because he needs him - and I can understand why.
"Nathan is the absolute example of a player who has developed himself to top level.
“He has done so well for himself and has become a really important player for both the Netherlands and Manchester City.
“I am proud of Nathan. He is so important and is such a great defender now."
