Netherlands manager Ronald Koeman is feeling as 'fit as a fiddle' after undergoing heart surgery.

The former Everton and Southampton boss was admitted to hospital last week with chest complaints.

"Such an event really helps bring you down to earth," he said.

"It was fantastic for me to see how many people showed compassion and how many sweet messages I have received.

"From acquaintances from the football world, from clubs but also from complete strangers. That really meant a lot to me and I would like to thank everyone for that.

"Meanwhile, I feel fit as a fiddle again and that means that I will be back giving it my all, as soon as the ball starts rolling again."
