The Three Lions topped Group L courtesy of a 2-0 win over Panama on Saturday and will next face DR Congo in the Round of 32 in what should be another tactical challenge.
England’s performances so far have been mixed, with two wins out of 4 so far and displays that have failed to impress supporters and pundits whose World Cup hopes are slowly fading.
Speaking to the BBC this week, Shearer revealed that he believes Tuchel is still working out the details of his side who are yet to blend together on the pitch.
“It feels like Thomas Tuchel is still searching for some solutions, three games in.
“You don't have to have all the answers, even at this stage of a tournament - injuries and suspensions mean teams always have to adapt ideas and personnel as they progress - but Tuchel has quite a lot to sort out before we face DR Congo in Atlanta on Wednesday.
“The reason Tuchel has tried so many is that he has not quite worked it out yet. Obviously the injuries to Reece James and Jarell Quansah at right-back have not helped and neither has Bukayo Saka not being 100% fit.
“But, for whatever reason, we have not posed a consistent threat down the flanks and constantly changing the back four has not helped our defensively stability either. We've looked uncomfortable whenever teams have attacked us, which is a worry."
Mexico or Ecuador would await England in the last 16 on Monday if they were to bypass DR Congo on Wednesday night. Tuchel will face a low block once more this week and if Shearer is correct, fans may be in for yet another uninspiring performance.
