I agree it's unlikely we'll see any major overhaul of tactics.I am trying to think of managers who actually adjust their tactics in any significant way on a regular basis? Is it just that teams eventually find out how to counter them? Spurs, for example, stormed the league at the start of last season before teams learned how to exploit it. Spurs then sign more players that fit the Ange system and they're going strong again. He never changed his tactics even when they were struggling. Glasner's comments in the presser that he respected AP sticking to his tactics and principles is probably a message that we're not going to see any major overhaul in tactics.
In terms of managers who have changed approach Vieira went from one 6 and two 8s in midfield to two 6s and one 8.
Sadly this didn't work in making us either more solid defensively or more potent offensively.
Eventually he left with a whimper.
We're led to believe that Glasner is addressing our current scoring malaise by addressing this in training, as opposed to making a wholesale change of system.
Taking into account that Chris Wood alone has scored more goals this season than our team put together, our attacking attempts clearly need improvement.
However, it's unlikely that e g Mitchell will suddenly start to hit a stream of inviting crosses or that, in the absence of Wharton, the midfield will be able to provide the penetrating forward passes that the strikers need.
