He could be handed a lifeline in Bayern’s next match against RB Leipzig on Saturday. Tuchel is wrestling with an injury crisis in defence, with Alphonso Davies, Dayot Upamecano, Bouna Sarr, Sacha Boey, Noussair Mazraoui and Konrad Laimer all unlikely to be available.
Dier is being considered for a starting berth at right-back, with Joshua Kimmich and Raphael Guerrero both tempting Tuchel also. Kimmich and Guerrero would both be out of position, but impressing in a problem area for Bayern could convince the club to keep Dier beyond his loan.
As an England international he would likely have plenty of interest back in the Premier League, but a deal at Bayern would allow him to compete for Bundesliga and Champions League glory alongside Harry Kane.
