In a bonkers 2020, recent shouts of Mauricio Pochettino to Celtic have arrived to cap this year as one of the most bizarre in memory.

The former Spurs boss has been out of work for a year now and Dundee midfielder Charlie Adam has now called on the Parkhead board to install the Champions League finalist as manager if Neil Lennon leaves his post.

In fairness, the 2016 arrival of Brendan Rodgers in Glasgow's east end did shift the Overton window of what kind of appointments were possible in Scottish football, reinforced to a similar degree by Steven Gerrard pitching up at Rangers two years later.

But former Southampton and Tottenham boss Pochettino seems an obvious bridge too far, for many reasons.

Here are just four.

Mammoth salary

Pochettino was dismissed by Tottenham Hotspur in favour of wily Premier League veteran Jose Mourinho one year ago.

The Argentinian boss still had a contract set to run until 2023 and it's claimed he's still earning his £8.5m-a-year Spurs salary until he finds a new gig.

Pochettino won't want to replace that kind of money with the comparatively small wage Celtic would be able to pay him and it's likely he's spent a full year out of the game because more lucrative openings haven't yet developed.

In the throes of the Covid-19 cash crisis his former club even reportedly asked him in April to accept a wage cut for the job he left five months prior.

That shows the type of financial demands he asks of his clubs and surely the Hoops couldn't match that.

Elite ambitions

Pochettino just missed out on silverware in England on a number of different occasions.

His Spurs machine was still in its infancy back in 2016 but they ran shock winners Leicester City the closest until the final few games of the season, when the ill-mannered 'Battle of the Bridge' draw against Chelsea sealed their fate as also-rans.

Even before that, his side finished League Cup runners-up to Chelsea in 2015.

Then there came the biggest heartbreaker: the miraculous run to the Champions League final, with last minute drama against Manchester City and Ajax on the way. It all ended in pain as they fell to Liverpool in the final.

Those three close shaves will no doubt have Pochettino hungry to return to English football and win his first big managerial trophy.

Real Madrid links

Managers of Pochettino's calibre are always going to be linked to many big jobs.

But unlike others, he's not been shy in responding to the speculation.

Back in September, he toyed with the idea of earning the Real Madrid job and said: "I don't know if I will ever be coach of Real Madrid because football takes you where it wants to but for sure, it's my dream.

"If it's not the best, it's among the best clubs in the world. It has a great history and I think I'm no different from other football professionals.

"Any coach would have on their dream list to guide Real Madrid."

With Los Blancos potentially attracting him back to La Liga - where he began his managerial journey with Espanyol - it would be hard for Celtic to compete.

Lennon is being backed

The news of a Zoom call between Lennon and Parkhead power-brokers Peter Lawwell and Dermot Desmond suggests they're sticking with their man for now. 

They seem reluctant to let go of the Northern Irish boss and in these testing times of Covid-19, even if he goes it's unlikely such an expensive replacement will arrive.

Whether fans like it or not, it seems like Lennon is here to stay as he tries to revive the club's season. 

Clearly the focus is on domestic matters - that the trigger is yet to be pulled despite an embarrassing exit from Europe is proof of that.

He will ultimately be judged on Celtic's performance in their attempt to make 10 In A Row and the powers that be are happy to ride out the current run of form for now.
