Gareth Southgate is soaking up the plaudits after masterminding England to another semi-final.
The Three Lions booked their place in the last four of Euro 2020 on Saturday night after a 4-0 victory over Ukraine.
The match offered yet another change in formation and personnel from Southgate, who has made a habit of keeping his opponents guessing throughout the tournament.
In the opener against Croatia, he sprung a surprise with Kieran Trippier at left-back, before opting for more offensive options on the flanks against Scotland, bringing back Reece James and Luke Shaw.
The Czech Republic clash saw heavy rotation, before a switch to a 3-4-3 to match Germany's shape, stunting their dangerous wing-backs and using Kyle Walker's pace to match the considerable speed of Timo Werner.
Against Ukraine, Jadon Sancho was thrown in from the start, with Southgate pinpointing the need for width from the right against a narrow Ukraine back five.
Remind you of anyone? Just like Marcelo Bielsa, Southgate's tactical flexibility has one constant. Kalvin Phillips.
The Leeds United midfielder has been the lynchpin to the Whites' success under Bielsa and he's now becoming an undroppable for Southgate and England too.
The tactical flexibility and versatility of Phillips, which he has honed under Bielsa, is a manager's dream. Jordan Henderson is fit again but the Liverpool captain, who has won the Premier League and Champions League in two of the last three seasons, can't find a way in.
Whether it's a box-to-box role that saw him create the winning goal against Croatia, rolling back to his Leeds debut season, or in a double pivot against Germany, where he has become integral for Bielsa, Phillips has ticked every box.
With a squad filled with players full of tactical flexibility and understanding, Southgate has been allowed to tinker, a la Bielsa, to the maximum degree to find the right combination to match his opponents.
Casting back to the World Cup three years ago, England were rigid in their 3-5-2 approach, a system that failed to get the most from their attacking options but somewhat applied a huge plaster over their leaky defence.
Whilst Southgate was unable to call upon any game-changers from his bench against Croatia at the Luzhniki Stadium in Moscow, Jack Grealish and Phil Foden didn't even make it from the bench against Ukraine.
At times, the cries from the English supporters have been to 'let the opposition worry about us' but Southgate's record in knockout tournaments speaks for itself, especially compared to his predecessors.
It's a leaf from the book of Bielsa, making it no surprise that one of his Leeds favourites is the heart and soul of this England side.
