Speaking to MUTV, Ole Gunnar Solskjaer said: "We're adding more and more players now. Dean Henderson is back in training which is good for us, he won't be ready for the Brentford game.
"Diogo Dalot and Donny van de Beek have trained and they're ready to play a part in the game, I would think they'll be subs. Bruno Fernandes is back in training. He's not ready to join the game yet, but he's not too far.
"The training group is bigger with more quality and, hopefully, we'll add layer to layer. Of course, the season starts quickly and we haven't got time to wait for anyone, whoever is the fittest and in the best shape will be in line to play."
Both Henderson and Bruno are back in training after their extended post-Euro 2020 breaks although the Portuguese midfielder has only returned recently.
The Brentford clash will be Manchester United's third pre-season game of the summer, with the Red Devils beating Derby County (2-1) and losing to Queens Park Rangers (4-2) earlier this month.
