Wellington Silva has enjoyed his training stint with Arsenal.
The Fluminense striker won't officially join the Gunners until the New Year.
He wrote in his blog for Globoesporte: "I know that it will be really difficult to get used to life in England, above all the weather, the language and food.
"Therefore I am taking English lessons and am going in search of new experiences. During this period I have already played in four friendlies for Arsenal's B team. We won three and lost one. I managed to score a goal in our match with Manchester United last week.""
