Romero, who never looked fully settled during the game, was at fault for Bafetimbi Gomis’ winner in the 65th minute after meekly letting a near post shot trickle past him.
While the other four signings Man United have made this summer have quickly settled in at the club and endeared themselves to supporters, Romero continues to look shaky.
Speaking on Sky Sports after the game, Neville scrutinised the Argentine’s poor decision making.
The error, which ended up costing United the game, is further evidence of Romero being far from an adequate first-choice goalkeeper for Louis van Gaal’s side.
United supporters thought that Romero was drafted in to act as cover for David De Gea, but as the Spaniard continues to be ostracised in the midst of the ongoing transfer saga with Real Madrid, Romero has started all of United’s first six fixtures.
Aside from a few bright moments against Tottenham Hotspur and Club Brugge, the Argentine has invoked high levels of uncertainty amongst supporters despite having a commendable four clean sheets under his belt. As the transfer window comes to an end, United fans will want to see speculation surrounding De Gea eradicated which would subsequently pave the way for the reliable Spaniard to come back into van Gaal’s starting XI.
