Chelsea forward Alvaro Morata warned his team-mates Lionel Messi would be unstoppable in their Champions League tie against Barcelona.
The Premier League outfit will host the first leg of the last-16 tie at Stamford Bridge on February 20.

Morata left Madrid last year in a deal reportedly worth £60million, having struggled for game time at the Santiago Bernabeu.
