#4 Marc-Andre ter Stegen
Barcelona's total dominance of football matches means that very rarely do opponents get opportunities to test their goalkeepers, as most of the game is usually spent in the opposition half.
In such circumstances, maintaining concentration to pull off saves when called upon despite having nothing to do for the majority of the game is of optimum value. Marc-Andre ter Stegen ranks highly in this regard, as the 27-year-old maintains a high level of concentration and performs his duties when called upon.
His pristine ability with the ball at his feet also means that the German international serves as the initiator of many Barcelona attacks. He possesses excellent reflexes and dominance in the air which sees him installed as one of the best goalkeepers in the world at the moment.
Great goalkeepers help clubs win titles, and on current form, there are not many goalies better than Marc-Andre ter Stegen. Having inspired Barcelona to a treble in his very first season with the club, the former Borussia Monchengladbach man would be raring to go once again.
