Chelsea forward Willian has heaped praise manager on Jose Mourinho, claiming "working with the Portuguese boss is a learning experience on a daily basis".

The Brazilian international joined Chelsea from Anzhi Makhachkala in summer 2013 after the Blues beat Tottenham Hotspurs for his services, securing a reported £32m deal.

Willian believes he has since developed into a much better player thanks to Mourinho, while last season he also managed to score 4 four goals in 25 Premier League appearances.

"Working with Jose Mourinho is a learning experience on a daily basis. He demands a lot but is very specific and precise with his requests," Willian said, according to Chelsea official website.

"I'm learning a lot, that has helped improve my game and made my transition to the national team easier."

After playing the in World Cup for Brazil, the winger has struggled to secure a fixed place in Mourinho's line-up during the start of the new campaign.

However, the boss handed him a fresh chance on Saturday during the 3-0 victory over Aston Villa, and he responded with an impressive performance, scoring one goal and providing Oscar the assist for the opening strike.

Willian hopes to replicate this form in the coming games to become established in the line-up.

"I think I have to prove myself on a daily basis while I'm at Chelsea, kill a lion each time, and I'm dedicated to that mission, to give my best," he said.

"The expression (kill a lion) comes from Brazil; when I started playing my dad would use it all the time as a way of instilling confidence in me and showing that if you work hard every day results will occur."

Mourinho praised his last performance against Villa and may hand him a new chance to prove his worth in the Champions League game against Sporting Lisbon on Tuesday night.

Speaking about the game, Willian said: "It's a difficult match, they have quality players. It's a tough challenge; we respect their club and team but we've come here to collect the points."
