“We’re a lot more focused defensively and we’ve seen in these last few games what we can do,” said Yedlin, who joined the Black Cats on a season-long loan deal from Premier League rivals Tottenham Hotspur in the summer transfer window.
“As a defender, that’s our main focus – to not concede goals. I think the gaffer has definitely brought a more defensive approach on the training ground and that’s helped us.
“The guys up front are doing great work – Jermain (Defoe), Duncan (Watmore) and (Steven) Fletcher - and scoring the goals we need.”
Allardyce is well known for being a safety-first manager, and that is exactly what Sunderland need right now.
The former West Ham United and Newcastle United manager has made Sunderland stronger at the back, and results have been positive of late.
Sunderland have won their last two Premier League games without conceding a single goal and scoring three.
Of course, the Black Cats have given away chances to the opposition, but the key point is that they have not allowed their opponents to capitalise on them.
Allardyce’s side are 17th in the Championship table at the moment with 12 points from 14 matches, just two points above the relegation zone.
