The West Ham shot stopper recently qualified for Euro 2016 with the Republic of Ireland.
The shot stopper has had to settle for a place on the bench in Slaven Bilic’s side so far this season, with Adrian firmly the number-one choice.
He has, however, enjoyed game time with the Republic of Ireland, playing a big part in their recent success, with Martin O’Neill’s side beating Bosnia and Herzegovina to reach the Euro 2016 finals next summer.
Randolph describes that moment as a career highlight and says his move to the Hammers over the summer has been key to him making a breakthrough on the international stage.
"I’d go as far as to say that helping the boys to qualify for the European Championships next summer is my career highlight," he told whufc.com.
"I owe a lot to everyone at West Ham United who has helped me since I joined, I truly believe I wouldn’t have been given my opportunity at international level if I hadn’t made the step up to the Premier League."
With the international break now done with, focus now turns back to the Premier League for Bilic’s side.
Up next this weekend are London rivals Tottenham Hotspur, during what will no doubt be a huge clash for two sides who have already hugely impressed in the league this season.
West Ham and Spurs sit fifth and sixth in the table respectively, both sides eyeing a potential Champions League place next term if results carry on as they are.
It will be the first taste of a London derby for Randolph and he admits he can tell how important it is to everyone at the club.
"Talking to the lads who have been here for a while, you can tell how important it is to everyone at the club," he added.
"There’s a special atmosphere around the training ground whenever the big games come round and I am confident we will more than rise to the occasion."
