The person making the decision was reported to be John Murtough. And how well did he potentially know the credentials of Erik ten Hag? The answer to that is very simple without me even pointing to Edwin van der Sar or Steve McClaren. And that is due to Murtough having people working under him in senior recruitment roles who know Ajax very well and also know the coaching philosophy that Erik ten Hag wants to implement. And those people are Henny de Regt (was at Ajax for 18 years) and Marcel Bout (former assistant to Jupp Heynckes) who are both Dutch and are well versed in the positional play principles. And I predicted Murtough would go this direction and appoint ten Hag due to the above reasons. When you have people with such experience working with you then it's sensible to tap into their expertise on the subject.
We can't predict the future mate and we can't say for sure if any coach will go on to be a success. But I've always believed that Manchester United should always hire a coach who looks to implement a proactive, attacking brand of football with the aim of playing in the opponents half. And this is the first time we've done that since Fergie retired, and the appointment also meshes well with the modern game when it comes to applying the counter press.
So the difference between ten Hag and Pochettino is ideology. EtH wants to dominate the ball via positional play to exert zonal, positional and numerical superiority in a vertical axis, with the counter press as the secondary weapon, which is to attempt to win the ball back immediately after losing it.
Pochettino on the other hand places heavy emphasis on verticality and the counter press to win the ball back quickly high up the pitch to then counter attack the opponent. His teams on the ball aren't as well coached in comparison to ten Hag who places a heavy emphasis on positional play on the ball and positional play without the ball. Pochettino places heavy emphasis on positional play without the ball.
So for me ten Hag's ideals are superior and potentially more entertaining and it was the correct decision by the club because attacking football won.
