Bit casual on the first goal.
Rose was with Meunier sure, but its still a ball into Maguire's area of defence and whats he doing exactly? Just standing around. He's not defending or covering anything, the only threat is Meunier.
Jones was originally caught out of position on the attack down Belgium's left and other than him, Maguire is the last back to fill the holes in our shape/defence.
Maguire even points backwards to tell his teamates to drop back but he's the most casual one jogging back into position which he never gets to.
Several mistakes from England players there, Jones and Rose but yes also Maguire. Only Trippier and Stones came anywhere close to doing what they were supposed to during that move imo.
Thats just one example. But throughout the game when Belgium counterattacked at pace Maguire was out of position and doesnt get back. Another example is Meunier's volley in the 2nd half where Belgium break and when Meunier is making contact with his volley from almost half way inside the England box, Maguire is barely making it to around 20 yards from his own box (A yard from the D outside the 18 yard box). Again he's got caught up the pitch and the move has broken down and he doesnt have the pace or work ethic to get back into shape.
Having said all of that I do think he would be an upgrade on Jones although only in attacking ways. I would prefer we signed him instead of Toby assuming the fee is far more realistic than what Spurs want for him. He's not great but he is someone who is comfortable bringing the ball out of defence and can find a good pass plus hes very strong in the air. But he will also give the ball away at times. And he'll be out of position and not get back at times. We'll need to watch that and it needs to be reflected in his transfer fee.
