It won't be fair to underestimate a team before the game kick-off, maybe lets wait for the ball to bounce then we can say Tottenham Hotspur will be defeated by Liverpool but for now we can't be so sure on that.
Yeah is always not fair to underestimate a club but sometimes most people believe that underestimating a club gives them the courage, confident and the mindset that they are more bigger than the opposite club and when you reason that is actually true because only that will eradicate the fear in you but however it shouldn't be too over emphasized on the field because that's what causes failure for the team to win, however we will be witnessing EFL CUP Quarter finals by Tottenham Hotspur and Manchester United who has beginning to redeem themselves on there performance from their previous outcome, so I believe Tottenham Hotspur may likely be influenced by that into looking down on themselves, so any club that win between them goes straight to the semi finals.
