Assistant coach Gus added: “When you go to a club, especially in the middle of the season, you have to look at the stats and check where things might be going wrong and to try and put them right. The rest will follow.
“Everyone knows the quality of the team and everyone knows we can create chances and score goals because we have quality players.
“The problem was that we were conceding too many goals, a lot from set-plays, so we’ve been working on that.
“It’s important for the team to see that we can defend, to see we can keep clean sheets and then have the freedom to go forward. Even at the end of the game Michael Brown had a chance with a header and we want to make sure that doesn’t happen. Even if we are 4-0 up, we don’t want to concede a goal.”
Clean sheet in the bag, Gus was pleased with what was a fine display of attacking play, not least in forging ahead 3-0 in the first half.
“First of all, we needed to win,” he said. “Before the game everyone was thinking about the three points but it’s even better when you win and you can show everyone what you can do.
“We defended very well and denied the opposition chances while in the other box, we created chances and scored goals. It was a very good performance.”
Gus Poyet reiterated the importance of keeping clean sheets as he gave his verdict on the 4-0 win against Wigan.Head Coach Juande Ramos stressed immediately after Sunday’s convincing display that he took most satisfaction from keeping the opposition out in three of his four games in charge so far - Blackpool, Middlesbrough, Hapoel Tel Aviv and Wigan.
