Willian thinks he has passed the worst phase in his career and back to form.
The Brazilian joined the club on a threw year deal and admitted he had to go through the worst form in his career at the start.
After a great debut where he bagged a brave of assists against Fulham, he struggled to impose himself in games and looked like a passerby for the most part.
However that seem to have changed recently with the Brazilian winger bagging four assists in the space of two weeks to take his season total to seven.
In an interview with ESPN Brazil, he said: “It really was a very difficult start, apart from that first game against Fulham, where I had a good performance, I managed to make a good game.
“Even after that game there were some games that we won, I even had a good game, but then we ended up getting a bad streak.
“I also got a bad streak and I think my worst professional time to date, since I went up at Corinthians and was sold to Ukraine, then I arrived at Chelsea, without a doubt. This phase that passed now was the worst time that I think I lived as a professional.
“Of course, when you live in a difficult moment, you get really upset and try to find solutions, a way to improve, try to help the team.
“That’s what I’ve been doing all this time, I never stopped training, to work, to dedicate myself as much as possible.
“It took a little while to leave, but lately in the last games I’ve been playing well again, standing out with assists, playing well. So I’m happy to be back to find my good football.
Speaking about Arteta, despite the inconsistent season we have had, the summer signing thinks we are on the track.
“I think it has the potential to be a great project, it’s a great club, it’s in the hands of a good manager, it has everything to become one of the best managers in the world,” he said.
“Arsenal has everything to become a powerhouse again, to fight for titles, to play in the Champions League again, that’s what we players want.
“He always tries to talk to the players individually, even on the pitch, when he finishes training he calls the player, explains what he wants from the player, where the player should be, receive the ball… In other words, he is always trying to help the players to be better.
“There is no complaint about this, he is doing a great job, he is always looking for the players in the best possible way, giving them ideas, guiding them, showing them what he wants. Arsenal is in good hands.”
