Tottenham midfielder Rodrigo Bentancur was branded ‘stupid’ by Gary Neville after headbutting Luke Shaw and seeing red against Manchester United.Bentancur had only been on the pitch for 12 minutes as a second-half substitute, but lost his cool in the 78th minute when he lashed out at Shaw and was given his marching orders.He appeared to put a high tackle in on the left back, who was left fuming and chased his opponent down before pushing him to the ground.Bentancur responded by rushing to his feet and headbutting Shaw, resulting in a brawl between the players.’Madness from Bentancur,’ Neville said on Sky Sports. ‘Lack of discipline is not what he (Roberto De Zerbi) needs.’It’s stupidity. It really is.’ Rodrigo Bentancur (left) was sent off for Tottenham against Manchester United after headbutting Luke ShawThe Uruguay international had to be pulled away from Shaw, who was booked, by United defender Lisandro Martinez.A member of Tottenham’s coaching staff had to eventually escort him down the Old Trafford tunnel.Tottenham were already 1-0 down at the time, after dominating the first-half but failing to find the back of the net – a problem they have had regularly this season.Tottenham boss Roberto De Zerbi, meanwhile, said after the game: ‘I kissed Bentancur in the dressing room. We need this type of character. Football is character.’ United got their act together in the second period and went 1-0 up through Bryan Mbeumo, and Bentancur’s actions made it a near-impossible task for Roberto De Zerbi’s side to come back.They did, though, manage to do just that in stoppage time when Dominic Solanke converted a cross to leave Old Trafford stunned.Spurs are, though, still without a win this season. They did, however, move from bottom to 18th in the table. More to follow.
