In doing so, the Foals made good on a 4-2 home loss to the Istanbul outfit, who finish top of Group C nonetheless on 13 points, two clear of Gladbach. First-half strikes by Tolga Cigerci and Mike Hanke, the latter a penalty, and a welcome goal off the bench from striker Luuk de Jong in his first game back after injury sealed the win for Lucien Favre's troops at the Sükrü Saracoglu Stadium.
With qualification already secured and top spot in the group out of reach, Favre gave a few of up-and coming prospects a run-out, selecting Christofer Heimeroth in goal, Julian Korb at right back, Tolga Cigerci in a holding role and Branimir Hrgota and Alexander Ring in the wide positions down either flank.
Heimeroth was in action early on, tipping a lob from Selcuk Sahin over the bar after setting up the Fenerbahce midfielder himself with a poor clearance. Five minutes later Gladbach carved the first chance of their own, Mike Hanke foiled from a tight angle by home custodian Mert Günok after being played in by Hrgota. Even with nothing much at stake, both sides were pressing forward at every opportunity and midway through the first half it was the Foals who broke the deadlock, and in fine style.
Defining five minutes
Cigerci picked up a somewhat fortuitous ball from Peniel Mlapa on the edge of the box, but there was nothing lucky about the youngster's finish, a fine curling effort into the corner of the net. Five minutes later, the visitors had the chance to double their advantage when Henri Bienvenu put in a striker's foul on Hrgota inside the box. Old hand Hanke stepped up and drilled the penalty into the top corner and with less than half an hour on the clock, Gladbach were firmly in control of proceedings.
De Jong back among the goals
The rest of the half played out with Gladbach's reshuffled side keeping things tight and breaking with impressive fluidity when the opportunity arose. 2-0 it remained though going into the second 45 and the men from the Bundesliga continued to impress in the early stages of the half, with Finland international Ring blossoming in his central midfield role and several chances to build further on their lead going begging.
One of the best fell to Mlapa in the 63rd minute, the powerful frontman playing a one-two with Hanke but opting to go for goal himself rather than laying the ball off again, and Fenerbahce conceding nothing more than a corner at the end of it. Finishing aside however, it was an assured performance from the Foals against their table-topping hosts and they did eventually put the icing on the cake.
19-year-old Amin Younes, fresh off the bench, left three men in his wake before laying up a simple finish for fellow sub de Jong. Twelve minutes on the pitch, and the Dutch frontman was off the mark again.
