The Cameroon international has suffered a hamstring injury<\/a> and faces six weeks on the sidelines.<\/p>\n This raises a series of questions for Manchester United, with uncertainty already existing over the future of Altay Bayindir<\/a>.<\/p>\n United were already doing due diligence on potential goalkeeper signings, and there are a number of names in the mix, some familiar and others new.<\/p>\n Manchester United\u2019s first and second choice goalkeepers are Andre Onana<\/a> and Altay Bayindir<\/a>, both of who have question marks over them.<\/p>\n Transfer insider Graeme Bailey tells United In Focus: \u201cI am told that in an ideal world \u2013 everything being equal, if United had their way they would have replaced both Andre Onana and Altay Bayindir this summer.<\/p>\n \u201cOnana did have interest from Saudi Arabia and United were open to the idea, but now with his injury him moving is less likely.<\/p>\n \u201cBayindir I am told has not attracted the sort of interest this expected, especially back his homeland \u2013 but his exit is still not totally ruled out.<\/p>\n \u201cSo United\u2019s keeper search has been extensive given they could very well have been bringing in two.\u201d<\/p>\n In terms of direct replacements for Andre Onana, there are four names who stand out as options for the Red Devils.<\/p>\n Bailey tells UIF that these four are Emiliano Martinez<\/a> at Aston Villa, Lucas Chevalier at Lille, Porto\u2019s Diogo Costa and Parma goalkeeper Zion Suzuki.<\/p>\n United\u2019s ability to move for any of this quartet is dependent on finances and player sales this summer. To date the club have not sold a single player, and are focusing the existing budget on attacking players.<\/p>\n Bailey explains: \u201cTalks are ongoing over the current situation \u2013 it is something they are working on and seriously thinking about, but budgets are a worry.\u201d<\/p>\n Manchester United have an even longer list of potential replacements for Altay Bayindir, cheaper back-up options.<\/p>\n While intrigued by academy youngsters Radek Vitek<\/a> and Elyh Harrison<\/a>, before pre-season there is no assumption either will step up. That would be something they have to prove.<\/p>\n One new name on the club\u2019s list, United In Focus understand is Borussia Moenchengladbach goalkeeper Tiago Pereira Cardoso.<\/p>\n Cardoso, 19, is a Luxembourg international who made his Bundesliga debut this past season, where he has three clean sheets in five appearances.<\/p>\n Bailey explains: \u201cThey like Vanja Milinkovic-Savic and they have spoken about the option of him coming in. <\/p>\n \u201cThere has even been conversations of someone like a Sam Johnstone to return or Nick Pope who could be realistic challengers if they came in.<\/p>\n \u201cIn this bracket is also Botafogo\u2019s John Victor \u2013 who has been offered to them and they do think he is an interesting option.<\/p>\n \u201cThen there are the young options who they like and have watched, like and are keeping informed of they are the likes of Senne Lammens, Carl Rushworth and Anthony Patterson.<\/p>\n \u201cWe can also confirm they like Luxembourg international Tiago Pereira Cardoso at Borussia Monchengladbach.\u201d<\/p>\n Lammens and John Victor<\/a> have been linked to United with regularity over the past couple of months, along with Milinkovic-Savic.<\/p>\n United In Focus reported interest in Brighton back-up Carl Rushworth<\/a> earlier in the transfer window.<\/p>\n Former United stopper Sam Johnstone is another interesting name as a back-up. He was part of the 2011 FA Youth Cup winning squad<\/a>, and is currently on Wolves\u2019 books.<\/p>\n![\"Andre](\"https:\/\/www.newsbeep.com\/us\/wp-content\/uploads\/2025\/07\/GettyImages-2215015776-1024x687.jpg\")
