Manchester United travel to Brentford looking to make it two wins from two as Bryan Mbeumo is in line to make a return to his former club. The Cameroon international made the move to Old Trafford from the capital after Ruben Amorim's side had three bids rejected for his services. However, they will be without some key figures for the early kick-off against the Bees with Casemiro suspended following his red card in the first half of Saturday's 2-1 win over Chelsea . Successive wins would see the 40-year-old earn back-to-back triumphs for the first time since March when United beat Real Sociedad in the Europa League before following up with a comfortable win over Leicester City. However, Amorim is yet to embark on a sustained run during his difficult start to life in the dugout at Old Trafford. Last weekend's win was his 19th since replacing Erik ten Hag in the post, 10 months ago. Keith Andrews will be looking for a return to winning ways as he eyes his second Premier League win of the season. Brentford sit outside the relegation zone by one point after the first five matches and are winless since the second game of the campaign, when they edged past Aston Villa. Since then, there has only been a triumph in the Carabao Cup but the last four have brought two defeats and two draws. Here is the injury news and suspension latest for United ahead of the 12:30pm kick-off. Injury : Knee. The Man United head coach confirmed that the Argentina central defender will be out of the trip to the capital this weekend. Martinez is still recovering from a knee injury that required surgery in February. He has since returned to first-team training but no timeframe has been given for his return. Return date: N/A. Reason : Suspension. Casemiro will serve his one-match ban after picking up a second yellow against Chelsea. The Brazilian was handed his marching orders, despite seemingly winning the ball after challenging Andrey Santos. He is likely to be back in contention for the visit of Sunderland on October 4. Return date: Unknown Reason: Personal leave. Amad will not be featuring for United this weekend after being allowed to return home due to a family bereavement. Amorim said: "Amad is not here because someone in his family passed away so we are giving all our support and we understood it was important for him to have his time to return home." Return date: Unknown Injury: N/A. Noussair Mazraoui was a fresh injury concern to come from Friday's press conference as Amorim confirmed that he will miss the next two matches. "Nous is not going to be here until we stop for the international teams. He is out also," he said. The hope will be that he will return to the fold for the visit to Anfield to face Liverpool . Potential return date: Liverpool - October 19 Diogo Dalot will be fit to face Brentford on Saturday, the United head coach confirmed. The 29-year-old has missed the last two Premier League matches with a muscle injury but he could make his return this weekend. "Diogo is returning to the team," the Portuguese said. "And he is ready. "We have all the other players so we are in a good moment to go to Brentford." Return date : Brentford - September 27.
