The midfielder is in terrific form for the LA Galaxy at the moment.
The 22-year-old from California arrived at West Ham in 2009 from Sporting Santa Clara. He went on to play just the one game at West Ham – the infamous 5-0 defeat to Nottingham forest in the FA Cup back in 2014.
This summer he joined the LA Galaxy in MLS and has not looked back. He has scored a fantastic seven goals in 14 MLS games for his new club and is sharing the field with the likes of Steven Gerrard, Robbie Keane and Giovani dos Santos – so he has not done badly since departing The Hammers.
He has been talking to Sports Illustrated this week about his time at West Ham, even mentioning a time when his own team-mates were telling doomed Hammers boss Avram Grant to give him a game.
“It was a crazy time over there, mentally. It was just challenging. It was nuts … the love for the game was always there, but whether I enjoyed it as much, to be brutally honest, it was tough.
“I felt comfortable that I improved that I was good enough. I was ready. The guys were like, ‘I don’t know why they don’t give you a chance. One of the guys even asked Avram Grant, ‘Why isn’t Sebastian playing?’ because I was doing so well in training.
"I looked ready. I felt it. And I just shook my head. There’s five years of that, just literally getting pushed to the side. It was tough.”
Lletget is certainly proving himself in America. As we all well know however the MLS is not at the same standard of the Premier League – some would even argue The Championship is a higher standard.
Regardless, Lletget is proving to be one of the stars of the competition and with that in mind may very well one day be capable of playing in England once again.
Maybe then he can show West Ham what they are missing out on.
