#1 Marc-Andre ter Stegen (Barcelona)
Keylor Navas may have had an exceptional group stage campaign, but Barcelona's German shot-stopper edges him to the top spot on this list. The Catalan club's superstars have not been their best selves for quite some time now as a team, and tend to rely heavily on heroics by the generational talents in the squad.
Marc-Andre ter Stegen took the art of goalkeeping into a different dimension against Borussia Dortmund this term. The German, playing in front of his countrymen, engaged in a fascinating battle with Marco Reus and came out on top.
Barcelona endured a difficult night at the Signal Iduna Park, and the German side's direct counter-attacking style split the Catalan side's defence open several times. Reus would have had a hat-trick if it wasn't for his talented compatriot. Ter Stegen ended the match with a sensational penalty save and was Barcelona's best player on the pitch by a considerable distance.
Excellent performances against Inter Milan and Slavia Prague also helped Barcelona top a difficult group. With an impressive save percentage of 85 per cent in 6 matches in the group stages and a knack of bringing his best self to the most challenging of situations, Ter Stegen will be one of Barcelona's most important players going into the round of 16.
