Manchester United lost their only match of pre-season on Saturday but Ole Gunnar Solskjaer was still able to pluck two crucial positives.
Maguire has appealed against the court's decision - a move which, under Greek law, nullifies the conviction ahead of a forthcoming retrial in a more senior court.
"He hasn't been with us long, obviously he was another who was on global [duty], so he's done really well considering he's only trained with us for two days. He didn't have a long break", Solskjaer said. He is going to be our captain. We'll just leave Harry and his people and the process to run.
"Of course, Harry, as you said, had a hard summer", the United manager told MUTV.
"His break was different to others as we gave him a few more days and, after, he's come back and looked fine".
For me, he is a top, an absolute top human being and has always been a positive guy with the right values.
"There were some positives as well, some good positives like individual performances - I thought Deano showed his authority back there and he played like a proper Man United goalkeeper".
As Manchester United lost a friendly match against Aston Villa (1-0), the English footballer also shared his dissatisfaction.
Solskjaer said: "He's been training only a couple of days but he's a bright, bubbly character".
"They'll learn from it of course". We're ready for the season.
Gullit is of the view that Van de Beek and Klaassen have a similar playing style, which he feels is suited to attacking teams, and as such expects the Manchester United new boy's chances of succeeding to be good.
"It's been a odd time and a unusual world. I am not 100 per cent sure though". "As someone with the [playing] experience he has, in that sort of position, the manager is really on to the players about that in training, trying to improve that", he added. He said they're all set to win the trophy this time, even after having a short campaign before the season.
