England have learned lessons from Czech Republic setback, says Gareth Southgate

Gareth Southgate believes England will swiftly recover from their shock defeat to Czech Republic as they continue their Euro 2020 qualification campaign against Bularia.

England missed the chance to seal their qualification for next summer’s competition as they lost their first European or World Cup qualifier in a decade in Prague on Friday night.

The Three Lions are out to get back on track on Monday night and Southgate says he has been pleased with the reaction he has seen from his side.

Ahead of Monday night's Group A clash in Sofia, England boss Southgate told Sky Sports News: "We have a very honest group and are very self-reflective. They don't need me to tell them when they haven't played at the level they can.

"The key is always to recover from the result. We have to move forward and focus on tomorrow.

"I don't think defeats harm teams if the reaction is good. Then what you learn from defeats and the resilience from defeats are important parts of a player's career.

"I have always maintained that we have to qualify, and we haven't secured that qualification yet and our focus tomorrow is to get the performance and result."

There has been suggestion that Southgate may revert to a three-man defence which was used to great effect during last year's run to the World Cup semi-final, but the England boss remained coy on the idea.

"We are always looking at every aspect," he added. "We train and have meetings specifically on every area of the performance. There is always particular focus when an area is not going too well.

"In terms of tactical adjustments, we are always thinking about the best way to get the best players on the field, be the most dangerous, to get the best of our strengths but hide our weaknesses.

"We have done that over three years. We have tried different formations, we tried something first half the other night. In hindsight - because of the result - it didn't work but it doesn't mean it was wrong to have a go at it.

"If we don't ever think about evolving and trying those things then we will never progress as a team. We will always continue to make those assessments and the priority is to put in a good performance."
