Manchester City boss Mark Hughes remains concerned over the club's away form after their suffered another defeat on their travels at West Ham.
Just a week after claiming an impressive point at Anfield in a 1-1 draw with Liverpool, City's old failings returned at Upton Park.
Jack Collison scored the only goal of the game in the 71st minute when he lobbed home after Shay Given could only parry Savio's curling effort from the edge of the area.
Robinho saw one first-half effort saved by Rob Green and then missed a glorious opportunity, while Elano clipped the outside of the post late on with a free-kick which deflected off Lucas Neill's head.
"It was frustrating because we created good chances in the game and there were long periods when we were in the ascendancy," said Hughes.
"The away form has been a concern all year. We have done better in recent games and we were excellent against Liverpool.
"In that game we scored first, we were quite comfortable in the game and we got a positive result.
"Today we haven't been able to get that positive result. Perhaps we've played a little too much like the home team on the road this year and we've been caught on the break.
"I think that happened again here."
