Southampton coach Ronald Koeman believes the fact that his side has kept consecutive clean sheets show their improvement from last season.
Tadic’s penalty secured victory for Southampton against Sunderland, sending Koeman’s men to seventh on the log and unbeaten in away matches so far.
Koeman is only pleased with the fact that they’ve kept back-to-back clean sheets this season, seeing it as an improvement from last season’s exploits.
“The penalty was well taken by Dusan and that brings three points and the second clean sheet in a row, still unbeaten away from home – I think that’s fantastic,” Koeman told Sky Sports.
“We have experience from last year, you need wins and clean sheets but the second in a row is the difference compared to last season.
“In my opinion it’s a key point to finally reach a high position in the table.”
Koeman was impressed by his side’s display at the Stadium of Light but hopes they can improve in the final third next time out.
“I think we played well. It was difficult against the good organisation of Sunderland,” he added. “We had good pressing and this result is well deserved. “It’s difficult to create and maybe we were not that clinical in the box – not so good in our final pass.”
