Steve Clarke insists the time for Scotland to peak is in June.

The national team head coach was disappointed after his side lost 1-0 to Northern Ireland at Hampden on Tuesday night. However, the 60-year-old refused to get too low in his typical sort of fashion, as he pointed out that the time for the team to turn up is still months ahead.

Asked about the performance, he said on Viaplay: "Yeah, okay. Decent. Moved the ball. We had to create a little bit more in the final third - we had a lot of the ball. 

"We played against a very good, very organised Northern Ireland team. They got the deflection for the goal to give them a platform to defend even more than what they were before, and they were good on the night. We didn't quite create enough to get the goals back.

"Sometimes in the bad moments you learn more, so, let's see where we're at. You learn a lot about your players, team and what you're going to do in the summer. The time for us to peak is in June.

"I don't see signs that things are going terribly wrong. Football games can be decided on small margins. Tonight was decided on a small margin. We have to look at ourselves, try to be better and move on to the next games.

"We'll have a little chat after the game. I definitely won't speak to them en masse until we're back together in June. That's the next time we'll speak."

Andy Robertson rolled his ankle during the first half of the friendly encounter. 

It's a worry for the defender ahead of the title race run-in with Liverpool in the months ahead, but also with the European championships commencing in around 11 weeks.

Clarke said: "He's obviously come off with an injury so we'll assess it and see how he is, he'll go back to his club and they'll look after him."

Then asked what his hope is for the next international camp, he added: "Everybody fit and well, ready to go. That's it. Short, sharp and simple. I'll watch games and I'll get my selection. Hopefully, I make the right selection and hopefully, I've got a full squad of players to choose from, then we go to the tournament."
