Premier League 2018-19, Chelsea vs Bournemouth 2-0: 5 Talking Points

#3 Marcos Alonso continues to shine

Marcos Alonso is emerging as a key cog in Sarri's Chelsea

After Saturday's 2-0 win over Bournemouth, Sarri was full of praise for his Spanish left-back, who helped himself to another assist in an impressive performance.

"Alonso, at the moment, this position at left-back is maybe the best in Europe. [He has] Physical qualities at a top level, I think. He's doing very well in the offensive phase. But I also think he can improve in the defensive phase. If he improves that, he could be the best left-back in the world," said the former Napoli schemer.

While Sarri's comments contain more than a small dose of hyperbole, Alonso is still one of Chelsea's most potent offensive weapons — despite major questions marks over his defensive positioning.
