No chance for LFC game.Off the back of Romano's report, rival fans have mocked the midfielder's decision, informing the Brazilian that he will no longer be playing in the UEFA Champions League.United's poor past season saw them finish sixth, meaning they will be playing in the Europa League this campaign.They have been in dire need of midfield reinforcements following the departures of Paul Pogba and Nemanja Matic.Alongside this, the midfield partnership of Scott McTominay and Fred has come in for heavy criticism.The pair were part of the side that suffered a 2-1 defeat to Brighton & Hove Albion in Manchester United’s season-opener on August 7.McTominay was subsequently dropped ahead of the Red Devils' next game against Brentford.The Scot's absence paid no dividends as the Bees thrashed United 4-0 at the Gtech Community Stadium on August 13.Casemiro's arrival clearly couldn't have come at a more crucial time for Erik ten Hag's side, but rival fans have taken the time to poke fun at the impending transfer.Here are some reactions to the news the Brazilian has told teammates he's headed to Old Trafford:🇳🇱 Factos 👍👀@DaDavey__@FabrizioRomano Saying goodbye to winning trophies3546@FabrizioRomano Saying goodbye to winning trophies🇪🇸@AbdeGOAT@FabrizioRomano You gotta feel sad for him.
