Roberto Martinez felt Manchester United's 4-0 win did not correctly reflect Wigan's hard-working performance.
The Spaniard was pleased despite his side conceding four goals at home and felt his team had no choice but to attack the Red Devils and in the process leave their defence a little unprotected.
Javier Hernandez was in clinical form, bagging two either side of half-time, before Wayne Rooney and substitute Fabio added a fourth.
But Martinez was happy his outfit put United under pressure and said the Latics could have got themselves back into the game if strikes from Victor Moses and Maynor Figueroa had not been denied by a strong Edwin van der Sar.
"If you watch the game I don't think it (the scoreline) reflected the performance at all, but when you play against a Manchester United side and you want to win the game you need to take the chances and create," he told Sky Sports.
"I felt the first-half performance was very, very good. You go into the half-time one-nil down and sometimes it's really hard to take, (but) Man United today were clinical in their counter-attacks and they took advantage of it.
"I think now the squad is really, really strong and we've got very good options - a lot of competition, it's very good.
"As you saw today I thought we put Manchester United under pressure in certain moments of the game, but you need to take your chances."
Martinez also thought more should have been done about an off-the-ball collision in which Rooney was adjudged to have 'elbowed' James McCarthy.
"It's quite clear and the referee thought that as well - he gave a free-kick. Sometimes it's one of those incidents that if the referee didn't see you can feel frustrated about it but there's nothing you can do. Today he saw it," Martinez said.
"It's an off-the-ball incident, it's clearly an elbow. I just felt that we were very unlucky in that situation."
Reflecting on the game which sees Wigan remain in 19th spot, the Latics boss added: "We can do better and that's what we need to do."
