Willian leaving Chelsea

The 32-year-old, linked with a move across town to Arsenal, posted a farewell letter to the club's fans on Twitter.

"The time has now come to move on. I am certainly going to miss my team mates," he said. "I leave with my head held high, safe in the knowledge that I won things here and always did my best in a Chelsea shirt!"

Willian, who began his career with Corinthians in Sao Paulo, joined Chelsea from Anzhi Makhachkala in 2013 and made over 300 appearances for the club, winning two Premier League titles.

Willian praises 'excellent' Neymar

Neymar has been criticised for his theatrics in Russia, but the forward has netted twice and provided an assist in four games.

The Paris Saint-Germain star only made his return from injury last month and Willian feels Neymar is only getting better at the showpiece event.

"All of us know how important he [Neymar] is for our team and what his level of quality is," Willian said Wednesday.

"He has been playing better one game after the other as well. Our plan is to continue evolving, improving, until we get to the final if we are fortunate enough.
