No.
It may have been the first time England have played with three at the back in 11 years and they may have kept their third clean sheet in four games, but Southgate's men conceded more shots than in Thursday's win over Slovenia and lacked any sort of creativity in the midfield.
The England boss said before kick-off that he would change his formation in order to prepare for stronger teams in Russia next summer.
Speaking to 'ITV Sport', he explained: 'We have to pass the ball better, we have to keep possession and our connections have been better in this system.
'When we lost the ball the other night we were wide open on the counter and this should also help.'
After watching another uninspiring 1-0 win, the results from the experiment are inconclusive at best.
