LONDON – England have taken enormous strides since Gareth Southgate took charge but he says his squad still have "everything to prove" as they seek to build on last year's surprise run to the World Cup semi-finals.
Southgate's side began their qualifying campaign for next year's Euro 2020 finals with resounding victories over the Czech Republic and Montenegro to lead Group A ahead of Saturday's clash with Bulgaria at Wembley.
The growing sense of optimism was tempered somewhat in June when England's frailties were exposed as they lost 3-1 to the Netherlands in the Nations League semi-finals.
Victory over Bulgaria, and against Kosovo on Tuesday, will make qualification for next year's finals a near formality but Southgate believes England must not get ahead of themselves.
"We have everything to prove in terms of world rankings. We are competitive against any team but any team is capable of beating us," he told a news conference on Friday.
