Press Q

Goalkeepers are controlled only by the AI. They will try to catch the ball or intercept it when they are closest team member. You can enforce a slide tackle using Q on your goalkeeper, but use this carefully. When a goalkeeper does the slide tackle he always does it towards the ball and if the ball is moving fast, goalkeeper will miss it most of the time.

When your goalkeeper has the ball, you can make the regular pass or the lob pass using the appropriate buttons (S and A). Note, that you have a limited time for this: 3 seconds. If you do not make the pass in given time, then AI will take control of your goalkeeper.

A goalkeeper is immune to slide tackles, but can’t move with the ball.
