Harry Redknapp said the weekend's results illustrated the competitive nature of the Barclays Premier League.
The manager insisted after our 4-2 defeat that Bolton's performance was nothing less than he expected at the Reebok Stadium.
Elsewhere, a resurgent Liverpool beat title-favourites Chelsea, Newcastle toppled Arsenal at the Emirates and United needed a last-minute goal to beat Wolves at Old Trafford.
We step straight back into action tomorrow night (Tuesday, November 9) with another of those tough tests against Sunderland at the Lane.
Hammered 5-1 by Newcastle in the big local derby last week, Sunderland recovered to beat Stoke City on Saturday and move level on points with us in the table.
"The weekend just shows you how difficult it is to win football matches in the Premier League," said Harry. "It's a tough division and there are no easy games.
"You go to Bolton and you can expect exactly what we got, a tough game. Everyone had tough games. Arsenal against Newcastle, United against Wolves, Chelsea at Liverpool, it's so difficult to pick up wins and every game is so competitive.
"It will be tight this season. I've said before that I think it will be harder to get a place in the top four than last season.
"City look stronger than last season, they've improved, bought some big players, so they will be there again. Liverpool were always going to come good as well, always going to pick up. It will be difficult to keep them out of the top four."
