Birmingham were unlucky and should've got at least draw.
But this was a game between two teams with contrasting styles. Birmingham as usual went direct and utilised the counterpess to win the ball high up the pitch. And Sunderland stood off and looked to break on the counter by maintaining numbers in defence which opened up space for the second goal which Amad finished off superbly well.
The way Birmingham play there's no build up phase from the defensive to middle third. So instead they either look to go long with their keeper or one of their CBs looks for the wide receiver, which is normally one of the wingbacks who is high up the pitch waiting for the long diagonal ball. And when you approach games like that, Hannibal has to adapt and battle for the ball in a collective counter pressing approach.
I've watched most of Birmingham's games and it's been a effective approach which has yielded results. But it's a approach that requires the players to win the ball high up the pitch and to then quickly with a minimal amount of passes to get the ball into the box for a shot on goal. That doesn't really suit Hanninal as far as what he can offer on the ball, but I feel it's going to help him develop his off the ball pressing game which is important for any coach who looks to implement a proactive, attacking play style with pressing and counter pressing capabilities. And Birmingham City currently don't look to build play through the midfield, but they do look to press high and that I feel is only going to benefit Hannibal.
And under a coach like ten Hag, it's going to be extremely important to bring the intensity and pressing. And in that regard I feel he's coming along really well.
For Sundeland's second goal, Hannibal went to press the opponent and the Sunderland player evaded the pressure and played a brilliant ball to Amad who was in space to finish with aplomb. But that's something he will learn with more games and added experience. But I would honestly rather see him defend high up with a element of risk, rather than sit back and play on the counter, because Erik ten Hag won't want the players to do that in the way he wants to control the game, both on the ball and off the ball.
