Onana can be tested for another year, but they need to bring in the best players in defense to avoid repeating the mistakes they've made. Despite their strong attack, they still haven't secured the solid defensive players they need. Manchester United is hungry for success and has been years away from achieving their championship ambitions. This will need to change this year.
If you're a Manchester United fan you'll never mention that, Onana tested for another year? No no no. His injury is an opportunity for Manchester United to go into the market and get a suitable goalkeeper and so far there are two options available for them to pick Emiliano Martinez of Aston Villa that's very ready and waiting for Manchester United to make a move, then Senne Lammens of Royal Antwerp F.C which the board just recently spoke of internally, they're both better choices to Onana, Martinez is Premier League proven but Senne Lammens is younger and a cheaper Alternative. If Manchester United can sign a striker, goalkeeper and an extra Midfielder then they're good to go, they already have many good options for defense.
