Ralf Rangnick has enjoyed a long and distinguished career in management which dates all the way back to 1983.
But the German's involvement in European football's primary club competition, the Champions League, has been limited to two brief spells as Schalke boss and a short tenure as Manchester United interim manager.
In fact, Rangnick's experience at top continental level only stretches to 11 games, though he does have a huge win in the knockout stages during the early 2010s sitting pretty on his résumé.
Below is every Champions League game he's ever been involved in as boss.
1. PSV Eindhoven 1-0 Schalke 04 (13 September, 2005)
Goals: PSV - Vennegoor of Hesselink (33')
Ralf Rangnick's first taste of Champions League football as a manager came at Schalke in 2005 after spells in charge of VfB Stuttgart and Hannover 96.
Was it a good start for the German? Sadly, no; Jan Vennegoor of Hesselink - one of the best ever names in football - bagging the only goal of the game in a narrow PSV Eindhoven win.
2. Schalke 04 2-2 AC Milan (28 September, 2005)
Goals: Schalke 04 - Larsen (3'), Altintop (70'); AC Milan - Seedorf (1'), Shevchenko (59')
Things got a little better two weeks later as Rangnick's side got off the mark with a point against AC Milan, beaten finalists in that iconic Istanbul final less than four months prior.
Two quick goals from Clarence Seedorf and Soren Larsen got the game off to a breezy start, before Andriy Shevchenko, the tournament top scorer that year, put Milan ahead.
S04 and Rangnick weren't to be denied a share of the spoils though; substitute Hamit Altintop bagging an equaliser with 20 minutes remaining.
3. Fenerbahce 3-3 Schalke 04 (19 October, 2005)
Goals: Fenerbahce - Luciano (14'), Nobre (73'), Appiah (79'); Schalke 04 - Lincoln (59', 62'), Kuranyi (77')
The entertainment continued in Rangnick's third group game, but he was still left searching for his first win after a thrilling 3-3 draw away at Fenerbahce.
Lincoln grabbed a quick-fire brace in the second half to put Schalke ahead, but Kevin Kuranyi's goal wasn't enough to prevent the visitors from being pegged back twice to earn just a point.
4. Schalke 04 2-0 Fenerbahce (1 November, 2005)
Goals: Schalke 04 - Kuranyi (32'), Sand (90')
Finally, at the fourth time of asking, victory for Rangnick as Schalke downed Fenerbahce 2-0 in the reverse fixture.
Kuranyi was on the mark again, as was Denmark legend Ebbe Sand, who secured the points in stoppage time.
5. Schalke 04 3-0 PSV Eindhoven (23 November, 2005)
Goals: Schalke 04 - Kobiashvili (18' pen, 73', 79' pen)
The good times continued three weeks later when Schalke breezed past PSV Eindhoven in a routine 3-0 win.
Levan Kobiashvili was the hero on the night for Rangnick, bagging a hat-trick that included a first and second half penalty.
6. AC Milan 3-2 Schalke 04 (6 December, 2005)
Goals: AC Milan - Pirlo (42'), Kaka (52', 60'); Schalke 04 - Poulsen (44'), Lincoln (67')
Despite winning their previous two group games, Schalke needed a positive result against Milan because of PSV's win over Fenerbahce in the other matchday six fixture.
Rangnick's side would fall short in Milan, dropping into the UEFA Cup (as it was known then) after a 3-2 loss at San Siro; Christian Poulsen and Lincoln's goals not enough to stop Kaka from leading the Rossoneri to victory.
7. Inter 2-5 Schalke 04 (5 April, 2011)
Goals: Inter - Stankovic (1'), Milito (34'); Schalke 04 - Matip (17'), Edu (40', 75'), Raul (53'), Ranocchia o.g (57')
Rangnick was sacked by Schalke after that group stage elimination, and he wouldn't sample the Champions League again until six years later with....Schalke.
Drafted in to replace Felix Magath following a lengthy spell at Hoffenheim, he got straight back into the swing of things with a crunching 5-2 win over holders Inter at San Siro.
Joel Matip and Raul were among the scorers on a famous night for the club.
8. Schalke 04 2-1 Inter (13 April, 2011)
Goals: Schalke 04 - Raul (45'), Howedes (81')' Inter - Motta (49')
A week later, Schalke sealed a convincing 7-3 aggregate win with a narrow 2-1 victory at the Veltins Arena.
Raul again showed his prowess on European football's top stage, before Benedikt Howedes ensured Schalke's, and Rangnick's, passage through to the semis with a late winner.
9. Schalke 0-2 Man Utd (26 April, 2011)
Goals: Man Utd - Giggs (67'), Rooney (69')
Rangnick's first experience of facing an English side in the Champions League ironically came against Manchester United, who proved to be far too strong over two legs for Schalke.
The first leg of their semi final, played in Germany, was settled by quick-fire goals from Ryan Giggs and Wayne Rooney, who gave United a 2-0 advantage to take back to Old Trafford.
10. Man Utd 4-1 Schalke 04 (4 May, 2011)
Goals: Man Utd - Valencia (26'), Gibson (31'), Anderson (72', 76'); Schalke 04 - Jurado (35')
Rangnick's Schalke were then overwhelmed in the second leg at Old Trafford, crashing to a 4-1 defeat on the night and a 6-1 loss on aggregate.
The tie, which was over as a contest after goals in the first half an hour from Antonio Valencia and Darron Gibson, proved to be Rangnick's last game as a Champions League manager for a decade, as he walked away from the club four months later citing chronic fatigue syndrome.
11. Man Utd 1-1 Young Boys (8 December, 2021)
Goals: Man Utd - Greenwood (9'); Schalke 04 - Rieder (42')
Rangnick's first game back in the Champions League was as interim manager at Manchester United, having succeeded the sacked Ole Gunnar Solskjaer.
The Red Devils were already through to the knockout stages, and a much changed side were held to a 1-1 draw by a spirited Young Boys side. United won the group and were paired with Atletico Madrid in the last 16.
