Manchester City boss Sven Goran Eriksson is delighted with the support fans are showing at Eastlands this season.
He told City's website: "Everyone wants to see the stadium sold out for every game, but I think the 40,000 that were here for Middlesbrough were fantastic, absolutely incredible.
"You can understand that they like what they see, and we like them as well.
"I hope they keep coming, if you play attractive football everyone wants to see that and at the moment we are doing just that."
