For the first time since 1958, Celtic have lost four home games in a row. Out of the Europa League, 11 points behind Rangers in the Scottish Premiership title race, and now out of the League Cup.

Sunday’s 2-0 home loss to Ross County led to fans gathering outside Celtic Park demanding Neil Lennon’s removal as manager.

What has gone wrong at a club that have won nine consecutive league titles and will claim a fourth consecutive treble should they beat Hearts on 20 December in the Scottish Cup final?

And, crucially, can Lennon survive this crisis to remain as manager?

How has the pressure built?

In August, Celtic suffered their earliest Champions League exit in 15 years after falling to a shock defeat at the hands of Hungary’s Ferencvaros in Glasgow.

Then, defender Boli Bolingoli was found to have broken strict Covid-19 protocols, earning the wrath of the club and leading to Celtic having two games postponed.

Amid that, though, Lennon’s side won eight of their first nine league games as they chased the fabled 10 league titles in a row. But then their problems really began.

They lost meekly 2-0 at home to Rangers, 3-1 against AC Milan in the Europa League and dropped more points in a 3-3 draw at Aberdeen. And, although they drew with Lille in France and beat Aberdeen 2-0 in the Scottish Cup semi-final, they have since been thrashed 4-1 home and away by Sparta Prague.
