Razvan Rat has revealed he never expected to be first-choice left-back straight away after talking to his manager, Sam Allardyce, reports Shakhtar Donetsk's website.
The Romanian full-back left Donetsk in the summer but has struggled to establish himself in the Hammers line-up.
Rat hasn't appeared in any of his side's three league games so far with his only competitive action coming in the League Cup as part of a weakened side against Cheltenham Town.
Joey O'Brien, despite being right footed, has kept the 32-year-old warming the bench following a strong end to last season.
However, the 89-cap international is not worried about his gradual introduction to English football.
"Even before the start of the season Sam Allardyce told me that in the opening rounds he will not field me in the starting lineup." he said
"This is normal. He wanted me to feel the atmosphere of the English Premier League. Still, it's a new league for me and a totally different level. The coach explained to me that I should first get a feel for the English Premier League, and then he will field me."
Following a disappointing loss at home to Stoke in the Hammers' last league fixture, Rat hopes that he will get his opportunity in the next league game away to Southampton, which follows the international break where his Romanian side take on Hungary and Turkey.
"Perhaps my debut will take place after my return from international duty. I am to take the field already in the matchday four away game against Southampton. At least I hope so." Rat continued.
Despite not having much action on the field, Rat revealed his fondness for his new club and how the atmosphere at Upton Park has helped him settle.
"Basically, West Ham is a very friendly team.
"All the guys were originally open and they helped me in every way to safely pass the adaption period."
