Tuchel's warning comes as England prepare to host Spain in the Nations League on Saturday, with Palmer's absence a disappointment given his recall to the squad earlier in the season. The head coach has made it clear that he wants commitment from his players, and Palmer's decision not to join up with the squad has left him questioning the 24-year-old's desire to play for England.
Palmer has only 14 caps for England, and his latest withdrawal has raised doubts about his future in the squad. Tuchel has not held back in his assessment of Palmer's situation, warning that the attacker misses too many camps with injuries. The head coach has also made it clear that he will focus on the players who are available, with Morgan Gibbs-White called up as Palmer's replacement from a holiday in Dubai.
England's Nations League campaign begins on Saturday, and Tuchel will be looking to his available players to make a statement against Spain.
