If giving up eight goals through the first two matches of the season tells a club anything, it's that they could use some help in defense.
True, Spurs were up against the two dominant sides from Manchester, but these are clubs they aim to be in direct competition with. Suffering successive demolitions at the hands of one's rivals must surely set off alarm bells for Tottenham's top brass, especially with mere days remaining in the transfer window.
Cahill has been the subject of transfer speculation over the past few weeks, to the point where Bolton manager Owen Coyle suggested the player's inconsistent form over the past couple games might be down to having his head turned.
At the time, it was believed that Arsenal were the leading suitors, but Tottenham's rivals have since been linked with a move for German defender Per Mertesacker.
Cue Tottenham chairman Daniel Levy, whom Sky Sports understands has offered out-of-favor defender Sebastian Bassong as part of a deal. It is also believed that a straight cash deal could be made if Bolton decide they could do without Bassong.
With William Gallas and Ledley King currently injured—the latter chronically so—manager Harry Redknapp has seen his remaining options, particularly Younes Kaboul, fail to impress in partnering Michael Dawson. A move for Cahill would add valuable depth to the center of defense and signal intent to keep fighting for a spot near the top of the league, as Spurs currently sit rock bottom.
