The thirst for silverware isn't quite so desperate in N17 anymore, but that special night in Bilbao may have sparked a hunger within the Lilywhites.
The League Cup was our previous trophy success before Ange Posetecoglou guided the club to Europa League glory last term. We've since reached the final on three occasions, and were defeated semi-finalists under Ange.
Thomas Frank's domestic cup record is spotty, to say the least, and whether the Dane can adequately mitigate a demanding schedule remains up for debate. However, the boss has far shuffled his pack smartly enough, and he has an opportunity to hand an array of fringe players chances to impress on Wednesday night, as we welcome League One side Doncaster to our glamourous modern home.
Here's how Spurs could line up for their Carabao Cup third round tie.
Tottenham predicted lineup vs Doncaster (4-3-3)
Goalkeeper & Defenders
Antonín Kinský (GK) – Some still suspect Kinský has a chance of developing into Spurs' No. 1 rather swiftly, and he should make his first start of the season here. However, he may not be particularly busy.
Djed Spence (RB) – There's a distinct lack of options at full-back, with Frank reluctant to use Archie Gray there as Postecoglou did last season. With Pedro Porro deserving a rest, Spence, who replaced the Spaniard late on at the weekend, will start at right-back for the first time this season.
Kevin Danso (CB) – Lucas Bergvall's are fine, but I've missed Danso's missiles into the box from the touchline. Ideally, though, we're not reliant on long throws to cause chaos against a side two tiers below.
Kota Takai (CB) – The Japanese international was set back by a foot injury in the summer, but he's returned to training ahead of this cup tie. The manager's desire to rest his two starting centre-backs means Takai could be thrust into the mix.
Jun'ai Byfield (LB) – I'm not sure where Frank will turn at left-back. He'll want to preserve Destiny Udogie for the weekend, Spence is already in, and Ben Davies is out injured. Can 16-year-old Byfield play there?
Midfielders
Archie Gray (CM) – Frank is an admirer of the young and versatile Englishman, but we've barely seen him since he started the first league game of the season against Burnley. Thus, this is a particularly important outing for Gray.
Pape Matar Sarr (CM) – I thought Sarr would be getting the evening off in midweek, but the manager instead opted to leave him out of his team at the Amex, and the dogged midfielder didn't feature at all. He could be used in a different role than what he's excelled in so far this term.
Xavi Simons (AM) – There could be minutes for the exciting Lucá Williams-Barnett on Wednesday night, given his form for at youth level and, most recently, the U21s. However, Frank may fancy giving Xavi an hour in the No. 10 role after his game-changing cameo on Saturday.
Forwards
Brennan Johnson (RW) – Johnson hasn't looked comfortable off the left thus far, and while he's pretty awkward down the right, the Welshman did much of his damage last term from this side of the pitch.
Mathys Tel (ST) – A 'dead leg' kept Kolo Muani out of action at the weekend, and Frank has confirmed he'll miss Wednesday's cup tie. So, with Dominic Solanke out and Richarlison likely to earn a breather, there will be another chance for Tel to impress. Let's hope Xavi provides him with ample service.
Wilson Odobert (LW) – Odobert didn't quite snatch his chance at the weekend with both hands, but there may be another opportunity for the talented young Frenchman on Wednesday night.
