Chelsea's decision to re-sign Romelu Lukaku for nearly £100million now looks like a "mistake", according to Glen Johnson - and one that could make the summer transfer window tough for Thomas Tuchel.
Lukaku joined Chelsea for £97.5million last August, a decade after he had left Stamford Bridge for more first-team action at Everton.
The Belgium international then signed for Manchester United in 2017 before leaving the Premier League for Inter Milan in 2019, winning Serie A with Antonio Conte as coach in 2021.
