Scotland captain Andrew Robertson says their friendly defeat to Holland wasn't good enough.

The Oranje defeated Scotland 4-0 on Friday.

Liverpool fullback Robertson said: "I'm feeling anger and disappointment. We can't come away to these big teams and play the way we did.

"We have completely opened up at the end. The fact we've walked off 4-0 is unbelievable. It's impossible for it to happen. We need to have a look at it.

"We can't keep doing this. In the last couple of games, we've shipped quite a lot of goals. People looking at that result will think it was one-sided. We need to take a look at it and sort it out.

"In the last six games, we've dropped our standards. It could have been 6-0 at the end. We need to get back to winning ways."
