(PHOTOS:PA via AP)Manchester United suffered one of their most embarrassing losses ever after the storied club was dumped out of the League Cup in the second round by Grimsby Town, a team from the fourth tier of English football after a dramatic penalty shootout needing 26 penalties. A livid Manchester United manager Ruben Amorim took a dig at his own players by praising Grimsby for being “the only team that was on the pitch.”Grimsby won 12-11 on spot-kicks with Bryan Mbeumo missing the decisive penalty. Manchester United were trailing 2-0 at halftime before goals by Mbeumo and Harry Maguire leveled the score at 2-2 and sent the game into penalty shootout at the modest Blundell Park on England’s east coast, a stadium with just a 9,000-seat capacity.On their Twitter account, Grimsby shared a poplar chant related to the club: “You’ve just been slapped by the fish.”Why this result is embarrassing for Man United?Manchester United had new signings worth 200 million pounds ($270 million) just in its attack for the game in the form of Mbeumo, Matheus Cunha and Benjamin Sesko. Cunha failed in the shootout by having his weak attempt saved and Sesko took United’s 10th penalty — only ahead of goalkeeper Andre Onana.After finishing 15th last season in their worst league campaign since being relegated in 1974, United, the 20-time English champions, had gone on a spending splurge in the transfer window.United are yet to earn a win in three games this season, after a loss to Arsenal and a draw at Fulham in the league.What did United coach Amorim say?“The best players lose because a team can win against any group of players,” an angry Amorim said, “and I think the (United) team and the players spoke really loud today, so that’s it. We lost, the best team won.”Amorim accused his team of playing “without any intensity.”Story continues below this ad“We were completely lost and it’s hard to explain and that’s why I think they spoke really loud,” he said.Asked what he meant by that specific comment, Amorim said: “I think it was clear for everybody what happened today.”© IE Online Media Services Pvt LtdTags:Man UnitedManchester United
