Former Russia national team manager Lenoid Slutsky has pinpointed why England have struggled at the international stage over the past few years.

England have boasted some of the strongest national squads in recent years but their performances during major international tournaments over the last two decades have been nothing short of disastrous.

Slutsky also believes that England possessed the best squad in terms of individuals during the last ten years but explains that the Three Lions fail to perform at the biggest stage due to mental fragility.

Slutsky said: "England have the best squad for the past 10 years. Dele Alli, Harry Kane… really strong squad. But, what's really important is seems to be a lack of confidence. I felt it when we played England. When you scored [in Marseille], after we conceded the goal and you dream only about losing 1-0.

"But maybe the players - they adapt mentally for the Premier League - can't adapt for the pressure of the World Cup or Euros. Having the pressure of the whole country is different from one club.

"You have some fantastic young players - Alli, [Eric] Dier, [Daniel] Sturridge - but there seems to be a lack of confidence when it comes to the national team. Reaching the finals is no problem but as soon as you get there, there seems to be a problem and that must be a mental problem."
