The Hungarian claims to have studied the England international's technique so knew what to expect, but emphasised the need to win with his side lingering in the relegation zone
The save kept the scoreline at 0-0 in a United-dominated first-half with the hosts growing frustrated, however, Bogdan's efforts only postponed the Red Devils' lead as Paul Scholes opened the scoring just before halftime.
The Hungarian international dived to his right, palming Rooney's spot-kick back into play after Zat Knight fouled Danny Welbeck, a miss that took the England international to four misses in his last eight penalties, something Bogdan was aware of.
Speaking to The Mirror, the 24 year-old said: “We knew where Rooney had put his last couple of penalties. I tried to guess right and I did.
“Of course, personally, it was a good performance, but you should always think things could be better.
"I made a lot of saves but when you do that it means they’ve had many chances. You get the feeling that if they keep coming they’ll score, and that was what happened.
“The most important thing is that we didn’t pick up points. We need to be focused, to believe we can stay up and we have to start winning.
"We have three home games now and, with the fans behind us, hopefully we can get points against Liverpool and Arsenal.”
He also commented on the departure of Gary Cahill to Chelsea, continuing: “Gary was a great player for us, everyone can see that, because he played for England and Chelsea wanted him.
"But it’s an opportunity for other players, like David Wheater, so they have to grab that chance.”
Bolton manager Owen Coyle also spoke about Cahill's move to London and insisted the Trotters wouldn't be forced into any knee-jerk signings, claiming what he already has is sufficient if the right player isn't available.
"We need to help the squad we've got," Coyle added. "But if we don't get anybody in, the group we have is still good enough to stay up.
