Newcastle played number of second string players away at Manchester City and still won, will they do the same against Tottenham?
Spurs supporters were desperately disappointed to have seen their side lose to the Magpies on Sunday, as they slipped into the bottom half of the Premier League, but that win did provide Alan Pardew's side with some confidence.
And the boost that Newcastle got was on full display last night, as they managed to knock out Manchester City.
It was a display which showed their new-found faith in their own abilities which had been dwindling after a poor start to the season.
How does this prove a positive for Spurs, though?
Well, the Lilywhites have been drawn against Newcastle in the next round of the competition and that looks a much easier task than beating City.
Although Spurs will have to be keen to avoid an upset, Pardew is unlikely to play his strongest team in the match - even if the competition is now in the quarter-final stages - and the London club will be the heavy favourites.
A win in that tie could put them in the semi-finals of the tournament and push them closer to lifting the trophy.
Spurs' season looks as if it may end in disappointment in the Premier League, with the side already having to play catch-up on the top-four, but winning the League Cup could provide them with a silver-lining.
Mauricio Pochettino has expressed his desire to win a trophy at White Hart Lane in the near future and this may be his best chance of doing so.
It is made markedly easier by the fact they will face a second-string Newcastle side rather than strong City team, too, and, although everybody at Spurs would have loved to achieved the three points on Saturday, maybe this can serve as a small consolation.
