On the day that Carlos Tevez finally signed for Manchester City, it is worthwhile noting what else City is doing to mix things up in the Premier League.
Firstly, there is the possibility (rated at 50/50) of John Terry moving North.
Secondly, the suggestion that a deal for Adebayor is all but complete.
Lastly, there are unconfirmed reports that City is interested in Xabi Alonso.
As welcome as all of these signings are for City, which would make them a force in terms of both English and European football, there are also statements to each of the top four teams that things have changed.
Making each of the top four clearly aware that they are no longer able to assume primacy in terms of transfers in Europe will surely come as a shock in both the boardroom and on the terraces.
Sir Alex Ferguson is clearly unhappy with Tevez and his decision to move to City. He has also apparently reigned in his own transfer dealings until the market has settled down.
Perhaps that could mean for several windows?
Chelsea is beginning to doubt whether John Terry will start the season in dark blue, with the possibility of him playing in Sky Blue no longer as crazy as it was only last week.
And now Liverpool is likely to feel the pressure of Manchester City's massive resources, as the eye is being run over Xabi Alonso.
For City to be in the reckoning for Eto'o or Kaka was always likely to make the headlines, but the more powerful story will come from the weakening of the top fours' squads (with no quality additions likely) and the significant strengthening of City's on-field options.
Although the dust is yet to settle, with more deals no doubt to be struck, what Old Trafford, Emirates, Anfield and Stamford Bridge residents are feeling is likely to be one of discomfort, concern or perhaps even fear for the coming season.
