#3 Tottenham would still be a Europa League club
Around the turn of the decade, Tottenham were Europa League regulars. Even when they finished fourth in 2012, Chelsea's champions league win meant they had to settle for qualification to Europa.
From 2011 to 2015, Tottenham continued to consistently qualify for the Europa League under different managers – neither big enough a club for Champions League cameos, nor small enough for mid table mediocrity.
The emergence of Harry Kane has slowly propelled them up the table. Of course, a certain Mauricio Pochettino has had a lot of say in it too, but Kane is the first real superstar Tottenham have had since the days of Gareth Bale.
Without him, Pochettino would still field a commendable set of brave young players – but they might lack the stardust to turn them into a Champions League club from a Europa League club.
