Manchester United goalkeeper David de Gea believes Real Sociedad will improve even further in front of their own fans this week.
The Spaniards host United at the Anoeta Stadium in the Champions League on Tuesday night and de Gea is banking on them being better than they were in the 1-0 loss at Old Trafford on October 23.
"We want to win on Tuesday and continue the good form we've shown in Europe so far," de Gea told the club's official website.
"We know that if we get the three points we'll have one foot in the knockout rounds, but it won't be easy. Real Sociedad showed they are a strong team when they came to Old Trafford and they'll be even stronger at home in front of their own fans.
"I'm looking forward to the match a lot. It's a great stadium and San Sebastian is a very special city. I think their fans will create a very good atmosphere so it should be an enjoyable game.
"It's always a good experience to go back to Spain and, of course, doing so wearing the Manchester United shirt makes me very proud. I've played for United in Spain against Madrid and Bilbao and it was very special."
