Manchester United have begun preseason under new permanent head coach Michael Carrick after a late-season revival secured Champions League return. Midfielders Andrey Santos and Youri Tielemans arrived for £85 million, with more signings expected. Early results include a loss to Wrexham and a 5-0 win over Rosenborg, with tougher tests against Atlético Madrid, PSG, Leeds and AC Milan before the Premier League opener at Hull City on Aug. 22.

Five key issues loom. First, finishing the squad rebuild — a third midfielder, striker and left-sided player may still arrive. Second, Marcus Rashford's future: Barcelona didn't trigger their £26m option, so he'll likely rejoin the squad, though his No. 10 shirt went to Matheus Cunha. Carrick, who knows Rashford from coaching under José Mourinho and Ole Gunnar Solskjaer, may revive him.

Third, managing Harry Maguire (turning 34 in March) and injury-prone Luke Shaw for Champions League fixture congestion. Fourth, restoring goalkeeper Senne Lammens' confidence after his World Cup error for Belgium. Fifth, integrating academy talents like Shea Lacey and Harry Amass, who scored in preseason, to provide depth without extra spending.
