A week is a long time in politics. Football politics. 

On Tuesday morning, Gianni Infantino was in an impregnable position as Fifa president, the most powerful job in football.

Now, after trying to sell stakes in Fifa competitions to private investments firms - apparently without the knowledge of anyone else - Infantino's position appears to be under threat. 

Uefa - Infantino's fiercest critic - dealt its trump card on Thursday by threatening to boycott all Fifa competitions, including the World Cup.

Now European football's governing body senses the opportunity to remove Infantino - and this is likely to be the best chance it will ever get.

But they're far from the only unhappy federation. 

Concacaf, the confederation Infantino worked so closely with to organise the 2026 World Cup, has called for a "full review" into the leadership of Fifa in light of Infantino's plan. 

Even more damaging, loyal countries in the Asian Football Confederation (AFC) shunned him too.

Then he was abandoned by two of his closest allies - and 

After Infantino backtracked in the early hours of Saturday morning, Uefa delivered another devastating blow by issuing a strong statement saying it had lost confidence in him.

The battles lines have been drawn. What could happen next?
