It is far too early to say how far off a title challenge we are.
Of our regular first XI this season, 6 are signings from this year (Adam, Henderson, Downing, Enrique, Carroll, Suarez). That is over half of the team. I think the time to review will be the end of the season. Some have got off to a great start, some we have only seen flashes of brilliance, but lets give them time before we jump the gun and say we need this, that, and the other.
We had a huge squad overhaul over the last 12 months, with many players leaving, and many coming in. We have seen some high profile exits, and some big money transfers. We aren't like City, who make a big money signing that doesn't settle quickly, they buy another. And had it not been for Tevez's fall out, Dzeko may have been dumped on the heap of "expensive failures" at City. But look at him now, now that he has been given a good run in the side.
We have to build, and give our players time to settle, not knee jerk into what we need for the title. This squad deserves a full season, see where we finish, then go from there. If we are lagging way behind the 4th place chase in January, then we need to make some big decisions. But there is 27 points up for grabs until the transfer window opens. 27 points for this squad to show they deserve to stay in the squad, stay in the team, and that we don't need any immediate additions to hit our target of CL football.
