Chelsea's Premier League pursuit of Liverpool has just become a lot tougher thanks to one man, according to Thomas Tuchel.
The European Champions recently added the World Club Championship to their trophy cabinet but are only third in the Premier League table, trailing the Reds and leaders Manchester City.
Expectations at Stamford Bridge under owner Roman Abramovic are always sky high, but former PSG and Borussia Dortmund boss Tuchel believes the arrival of Luis Diaz at Anfield only reduces Chelsea's chances of gaining ground.
