Joelinton fired Newcastle United a step closer to Wembley with the winner in an action-packed Carabao Cup semi-final first leg success at Southampton.

The Brazilian, who also saw a disallowed goal and was guilty of a bad miss, secured a 1-0 win for the Magpies by burying a low cross from substitute Alexander Isak with 17 minutes to go on a breathless evening at St Mary’s.

Saints thought they had swiftly levelled through Newcastle academy graduate Adam Armstrong but his bundled effort was ruled out for handball following VAR intervention.

Joelinton had a first-half effort controversially chalked off for an adjudged handball, while he wastefully blazed over with the goal gaping early in the second period. Southampton finished a frantic encounter with 10 men after defender Duje Caleta-Car was dismissed four minutes from time for a second bookable offence.
