Game changing subs?

[Super_Ally 0]

 

A UK Football Think Tank - they analysis stats - looked at substitutions.

 

'Like for like' changes make virtually no difference to how a game is going.

 

'Tactical changes' are 72% more likely to change pattern of game positively.

 

They also state that not changing tactics if game is not going well is a very British thing (not using blind bias but statistical data) and outmoded...basically if shape/system doesn't work after 5 minutes it won't after 35 or 75 either.

 

My own interpretation on the latter point: could this be why so many British managers over years have been 'cheque book managers'? Just a thought.

 

Finding source for the above.
