West Bromwich Albion striker Saido Berahino made it two goals in two games for England U21 in last night's 1-1 Euros draw in Finland.
Southgate was also pleased with the performance of Tottenham centre-forward Harry Kane.
"Saido had been a goal threat and we know that Harry's a goalscorer, so maybe that change of shape gives the opposition something to think about," said Southgate.
"It paid off for us, as we had that spell when Harry nearly gets the header and we hit the post when we were down to 10 men."
