The Spanish goalkeeper insists the Red Devils will look to win at the Etihad Stadium on Monday, despite knowing a draw will keep them in the driving seat for the title run-in.Manchester United goalkeeper David de Gea says his side do not know how to “park the bus” and will go for a win in Monday night’s crunch clash with bitter rivals Manchester City.United enjoy a three-point lead over City at the top of the Premier League with just three matches to play, but know a repeat of October’s 6-1 Old Trafford humiliation at the Etihad Stadium will see their advantage wiped out.A draw would be enough to keep Sir Alex Ferguson’s men in control, but De Gea insists the idea of playing for a share of the spoils is not even in their minds.“We won\'t park the bus or try to get a point,” he told Goal.com. “We don\'t know how to do it and that would mean giving them the advantage on the match.“We are approaching this derby as a final because it really is, but we have more chances than them. They need the victory and that\'s an extra pressure they could resent on the pitch.“I don\'t expect a crazy match but rather a tactical one. This is not a knockout tie but a match in which a goal can give you the title, so we have to remain calm.“This is the match of the season and we are planning up to the most minimal detail. We cannot fail.”“The ambiance will be electric and the fans will be against us but I won\'t be affected.“I have played at the Bernabeu, Camp Nou, Turkey, Greece and Italy. I actually play better in these situations.“My team-mates have been very motivated during this week\'s training sessions. We know what we are fighting for and we know that we will play a final tonight.“We won\'t think about losing but it would obviously be very hard if we finish the season without winning a title and after having the Premier League title in the tips of our hands.”A record 20th Premier League title would be a remarkable achievement considering United’s shaky form during the first half of the season.But since the turn of the year they have been relentless in their pursuit of City, with De Gea gradually growing into the No.1 shirt and playing a key role.Everton’s stunning late comeback at Old Trafford last Sunday has given Roberto Mancini’s men renewed hope, but De Gea insists United have not grown complacent at the top. “I think I have improved a lot since I arrived in England,” he continued.“My beginnings weren\'t very good or very easy but I feel a lot better now. Even the coach says so.
