Tunisia was forced into an early goalkeeping change.

Mouez Hassen was caught by Lingard in the fifth minute but remained on the field and even pulled off a fine save — clawing away Stones' header from Ashley Young's corner — before Kane scored.

Hassen, though, was forced off in the 15th and replaced by Ben Mustapha.

England and Belgium are the early front-runners as expected. But while England passed the sterner test, Belgium had the most comfortable start in its 3-0 victory over Panama.

England will hope the World Cup newcomers roll over as easily when they meet on Sunday.

The late priority in the warm-up for England was needing insect repellent. Mosquitoes and little bugs have been swarming across the city, creating an annoyance for players.
