After England's last-32 win over DR Congo former Three Lions forward Wayne Rooney said there are still "big concerns" - so how does manager Thomas Tuchel fix them?
Captain Harry Kane came to their rescue with two late goals in Wednesday's comeback victory, setting up a last-16 showdown with Mexico.
But questions remain from back to front, with the right-back spot and wide forward positions both up for debate.
Can Djed Spence be trusted at full-back? Did Anthony Gordon do enough to oust Marcus Rashford from the starting line-up with two assists? Do England risk Bukayo Saka's fitness?
