There is no quick fix: Manchester United fans may have to suffer in the short term before glory is restored to Old Trafford.
Liverpool identified Jurgen Klopp as the man to bring success back to Anfield back in 2015, gave him time and resources to implement his culture – and look at them now. They waited 30 years on the Kop between Kenny Dalglish delivering the title in 1990 and Klopp masterminding the next one in 2020.
I'm not suggesting United fans will have to wait three whole decades, but it's already nine years since Sir Alex Ferguson retired on the back of his 13 titles (plus three at Aberdeen). And after their Champions League exit against Atletico Madrid - where it looked like all the best players were on the pitch with no clear structure - they may have to go through a bit more pain before the good times return.
