Real Madrid goalkeeper Thibaut Courtois is confident he can be fit for the start of the La Liga season after suffering an ankle injury during training on Monday, sources have told ESPN FC.

Summer 2018 signing Courtois had established himself firmly as first-choice keeper for Los Blancos coach Zinedine Zidane through preseason in recent weeks, only to pick up "a grade 2 sprained ankle" at training, according to a Madrid club statement.

However, sources tell ESPN FC that Courtois believes the ankle knock is not serious, and he will soon be again available for selection.

Previous No. 1 Keylor Navas will now get another chance to impress in Madrid's remaining warm up games, starting in Tuesday's Audi Cup game against Tottenham in Munich

The Costa Rica international had considered leaving Madrid this summer, but a move to Paris Saint Germain fell through, sources said last week.
