Ohhhh, this is a very shrewd move on Khan's part. A bold stroke. Let's just start with the considerations regarding Fulham FC.
If he owns Wembley, he has a place for Fulham to play while Craven Cottage is given an even saucier, sexier upgrade from the one just recently approved. He's clearly got the money to make that happen.
Spurs have made a great case for using the added capacity of Wembley as a way to grow a fan base. So why should Fulham, clearly on course to earn promotion, be exempt from that process? They've got a huge star-in-the-making in young Ryan Sessegnon, someone you can build a team around. When they clinch promotion, they'll clearly have the grounds, to say nothing of the finances, to hold onto him. A year or two at Wembley, at can't-say-no ticket prices, might do wonders for their appeal to new fans.
As for any misplaced notion about moving the club, you don't leave that posh Fulham neighbourhood lightly. Fabulous place full of medical professionals. Demographics to die for. When the time comes, they'll move back and Craven Cottage will definitely be a 'Go To' destination. But no rush if Khan owns Wembley.
On another hand, he now controls the one stadium his much un-loved neighbours, Chelsea, would logically hope to move into when their stadium re-build is set to begin. In fact, that re-build may well conflict directly with the re-furbishing of Craven Cottage. So Chelsea might well be told to 'pi55 up a rope', Fulham need Wembley and actually own it. Oh, wouldn't that go over well in the west wing of the Kremlin?
Now, ponder what this means for Khan's NFL team, the Jacksonville Jaguars. He can comfortably move them full time into a grand, world famous stadium and the NFL owners will take one look at the choice - London vs. a scruffy norf Florida city that gave us Lynyrd Skynyrd - and giddily, laughingly make an instant decision.
By taking over Wembley, Khan is no longer in thrall to our beloved Daniel Levy to pay heavy rent for Spurs wonderful new MegaLane facility. He has a powerful bargaining chip to achieve lower rents if he should choose to play at MegaLane, which offers a perfectly tailored showcase for the NFL. But he is no longer over a barrel.
Which raises an interesting point of speculation. If the NFL thinks London is such a great marketplace, might it consider placing two full-time franchises there?
It's not beyond the realm of possibility. Two teams in London would not only create an instant rivalry, but make travel logistics for American-based clubs a lot easier. It would also set a strong foundation in place for an eventual European division with at least one team in Germany a very real prospect down the road. Again, natural, historic rivalries in that situation would stir interest.
A very interesting twist in the plot from a man who clearly sees bigger pictures than most others.
