Barcelona 3-1 Borussia Dortmund: 5 Things we learned from the game | Champions League 2019-20

#4 De Jong composed, Umtiti encouraging and Ter Stegen's importance

de Jong delivered an accomplished display in central midfield and continues growing in stature

Barca are through to the knockout rounds as group winners but other than Messi, have a select few players to highlight for their respective efforts on this occasion. The match could've changed completely if not for Marc-Andre ter Stegen's alert, important goalkeeping saves throughout. The hosts did a good job of soaking up pressure and combining to devastating effect in transition, but there was more to their display than the three goals.

Ter Stegen continues proving why he's arguably the world's best goalkeeper with match-defining interventions at crucial points: denying Schulz and Brandt from close-range, delivering an excellent fingertip save to tip Sancho's goalbound effort onto the crossbar and again proving a dependable outlet for the Blaugrana.

He makes these saves look so routine and straightforward that it's no longer surprising anymore - more expected of him as Barca's last line of defence. Nonetheless, if not for his efforts over the 90 minutes, this article would be written in a completely different tune.

As for Samuel Umtiti, the World Cup winner made his first 19-20 Champions League appearance having struggled with persistent injuries in recent months. It's fair to say since last summer's triumph in Russia, the defender's progression has stagnated and deciding to risk his knee hurt him in the long-term.

Nonetheless, with a suspended Gerard Pique watching helplessly from the stands, the 26-year-old started for the fourth time this term and it's easy to forget just how influential he was at the back prior to his injury woes.

Partnering compatriot Clement Lenglet at the heart of Barca's defence, he was one of the hosts' best performers while doing his reputation no harm at all with a steady defensive showing. He made one goalline clearance, block, interception and tackle, won four of five duels and completed 93.8% of his passes without committing a foul over the 90 minutes. It's a display that'll give him some much-needed confidence, given his lack of luck recently.

Speaking of best performers, Frenkie de Jong again starred as the brightest and most exciting of Barca's midfield trio.

Alongside Sergio Busquets and Ivan Rakitic, the 22-year-old was composed in possession, unafraid to take players on while releasing teammates with neat forward passes and an ever-present defensive figure too whenever Dortmund threatened. His match stats speak for themselves: 94% pass accuracy, four successful dribbles, seven duels won, 10 of 11 accurate long balls completed, three tackles and two interceptions.
