Mauricio Pochettino’s Spurs were in the box-seat to progress to the quarter-finals after Son Heung-min fired the home side in front on 39 minutes.
But Serie A giants Juventus drastically improved after the break and two goals in the space of two minutes from Gonzalo Higuaín and Paulo Dybala turned the tie on its head.
Tottenham pushed for an equaliser that would have sent the tie into extra-time, with Harry Kane striking the post with a header, but it was to no avail as Juventus held on to progress.
Allegri made two substitutions moments before his side began their comeback and a number of Arsenal fans believe this is further proof he should replace Arsene Wenger at the Emirates.
The Gunners have lost four straight games, including the Carabao Cup final against Manchester City, sparking fresh speculation Wenger will leave at the end of the season.
Arsenal fans like the look of Max Allegri:
Allegri turning things around.
Wenger will sit down and finish 5 packs of Eva bottle water settling for 1 – 0#FanLiveNG

Top manager Allegri. In game changes and substitutions have changed the game for them. Something Wenger hasn’t done in over 10 years!

Allegri's substitutions completely changed the game,meanwhile wenger in a losing position will wait till the 70th minute to bring on welbeck

Allegri should replace Wenger!

I wonder what Wenger thinks when he sees Allegri identify what is going wrong on the pitch, and then deciding to switch tactics mid-game to rectify it. Does he think that type of approach is blind luck?

You see what Allegri did? Wenger can NEVER do a thing like that. He’s too old fashioned. 2 changes in the 60th minute, changed the system, and now they’re ahead. Arsenal needs a modern coach, anyone who can NOT see this is blind!!!

Tactical nous. Positive changes from Allegri. Sign him up , let Wenger go.
— Nakalee (@odinaks) March 7, 2018
Allegri with a couple of changes and a tactical tweak which completely turns the game on it's head..
Not long after a game in which Wenger didn't even make a single substitution and we lost 3-0.

Allegri without a fully fit squad still made the right changes to turn things around and you are calling Wenger near me. If I blow you.

ALLEGRI MASTERCLASS Wenger could never!!!!
