The midfielder has been in good form for the Republic of Ireland under-21s recently.
He may have been born in Southend but the youngster represents the Republic of Ireland at international level.
He recently made his Republic of Ireland debut and was awarded man-of-the-match for a goalscoring display against Andorra. He picked up the MOTM gong once again for his performance in his second cap, a win against Lithuania on Friday.
He is now set to take on Italy this Tuesday where he will continue to try and impress for his nation.
He is clearly catching the eye. West Ham co-chairman David Gold has now Tweeted a message to the 19-year-old offering his support to the teenager:
Ireland face Italy under-21s on Tuesday, when Josh Cullen will be hoping to once again drive his nation to victory. dg— David Gold (@davidgold) October 11, 2015
Cullen signed a new deal at West Ham on transfer deadline day and it looks like he is pushing on to become a potential first-teamer in years to come.
