Ole Gunnar Solskjaer switched to a 3-4-1-2 for Tottenham on Saturday and had he not, it might have been Manchester United releasing a club statement on Monday.
The decision to drop 4-2-3-1 for the first time this season worked. United not only achieved their second clean sheet in 22 games but they did not allow Tottenham a shot on target.
This system may only be a stop-gap, because it means Solskjaer must sacrifice one of his attackers to add a defender. But it is a good way for a manager under pressure to extract some much-needed immediate results.
