Argghhhhh .. must not respond ... leave dead equine alone ... fudge it ...
Can we just be clear on this
Fact 1 - Football teams are not evenly matched - Barca, Bayern, Real are all a level above in talent, experience and squad depth to everyone else in the world as an example
based on that, you either believe
A. That winning mentality can overcome any gap in ability, in which case we should see the occasional non Spain/England/Germany/Italy side win the CL with their winning mentality?
B. Everyone bar those teams does not have a winning mentality, in which case is winning mentality a thing, or just the best players money can buy?
The reason Spurs hasn't won a trophy in 10 years is because for at least 6-7 of those, we simply weren't good enough -> Gomes, Friedel, Dawson, Vlad, Scott Parker, Kranjcar, Bentley, Jenas, Bentley, JD, Pav, Keane, Palacios, Lennon (and those were the better players) simply aren't trophy winning or title challenging level players. They all fit a West Ham, Everton type profile more than a top 4 profile.
Not good enough is a much better explanation that some imaginary mentality/bottler concept.
