Jamie Redknapp has branded Thomas Tuchel’s decision to leave Trent Alexander-Arnold out of England’s 2026 World Cup squad a “monumental mistake,” arguing the head coach had to be able to handle a creative full-back amid an injury-hit right side. England have emerged from Group L in control after beating Croatia and Panama and drawing with Ghana, but the positives on the table have come with growing concerns over depth in defence. Reece James and Jarell Quansah have both suffered injuries during the tournament, while Tino Livramento was replaced by Trevoh Chalobah on the eve of kickoff. That sequence has intensified scrutiny on Tuchel’s call to omit Alexander-Arnold, a selection Redknapp insists many saw coming once James’ fitness wobbled. Redknapp’s critique is rooted in England’s need for width and delivery against opponents who sit deep. Without Alexander-Arnold’s passing range, England have often had to manufacture width through advanced wingers and overlapping centre-backs, a compromise that can blunt their control in possession. The suggestion that Quansah could cover at right-back underlines how stretched the options have become, and it nudges the conversation back to balance: whether Tuchel has prioritised defensive solidity over creative incision down the flank. Tuchel’s supporters would note that England’s results have remained strong in Group L and that the team have shown adaptability, particularly against counterattacking threats from Ghana and Croatia. They also point out that James, when fit, is a complete modern full-back and that Livramento’s withdrawal forced a late recalibration. Still, with the knockouts looming and opponents inclined to compact the middle, Alexander-Arnold’s early crosses, switches of play and set-piece mastery could have been priceless tools to unlock low blocks. The injuries have already shoved England into contingency mode. Chalobah’s inclusion offers defensive security, but it naturally limits the crossing quality from the right. As England prepare for the next phase, Tuchel faces a tactical trade-off: keep the back line conservative and rely on midfield rotations and wingers to create, or introduce more adventure from full-back areas. Redknapp’s warning frames the stakes clearly—selection choices at right-back may decide whether England’s possession turns into chances when space is scarce. For now, Group L leadership buys Tuchel time, but the debate around Alexander-Arnold’s absence will only grow louder if England struggle to find width in the pressure of the World Cup knockout rounds.
