Southampton star Stuart Armstrong believes Scotland are steadily improving with each passing game.
The Scots take on Croatia in the final game of their group stage campaign at Euro 2020 this week.
If the Scots win the game, they have a chance of progressing to the knockout rounds, after losing their first game to Czech Republic and drawing with England.
"After the first game there was obviously a lot of disappointment surrounding the result," said midfielder Armstrong, per the Daily Echo.
"So we knew we had to get something from the game (against England), be that one point or three points. So to come away with what we set out to achieve was obviously massive for us.
"It sets us up for the final game of the tournament, keeps us in it.
"I think we're quietly sticking to our gameplan, building on our past two performances. We're steadily getting better.
"It's a simple game on Tuesday - it's a must-win for both teams. So it should prove exciting, it should be open, at times. It's all to play for."
