Gary Neville believes England are mismanaging their star players and has called on Gareth Southgate to start Kobbie Mainoo in the Euro 2024 knockout stages.

England topped Group C as a result of Tuesday's goalless draw with Slovenia, but they were booed off by their fans after producing another flat performance.

The Three Lions created just 0.8 expected goals (xG) despite enjoying 74% of the possession, the latter being their highest figure ever recorded in a major tournament match where they failed to score (since 1966 for World Cup and 1980 for Euros).

Southgate's team failed to attempt a single shot until the 30th minute, their longest wait for an attempt in a Euros match since 2000 (35th minute versus Germany).

The England boss only made one change to the team that toiled in a 1-1 draw with Denmark on matchday two, replacing Trent Alexander-Arnold with Conor Gallagher, as Phil Foden and Harry Kane continued to struggle in attack.

Speaking in his role as a pundit for ITV Sport, Neville said: "England have Cole Palmer, Bukayo Saka, Jude Bellingham, Kobbie Mainoo, Phil Foden… massive, massive talents and we cannot afford to mismanage them," he said.

"We are the only country in the world who continually ask, 'where can these players fit?'"

Manchester United midfielder Mainoo had a positive impact when he replaced Gallagher at half-time, and Southgate feels he should start Sunday's last-16 clash, which will pit England against a third-place finisher from either Group D or E.

"Every time England made a change, they got better," Neville said. "I am certain Mainoo will start the next game.

"Southgate thought Gallagher was the option for energy, but it was quite obvious we needed someone on there to get us playing and Adam Wharton is capable of doing that as well.

"The more substitutions we made, the less rigid we looked. We looked so basic in the first half, it was a struggle to watch that and I think we moved forward in the second half. We did not get the result, but there were glimpses of what we can be."
