"Harry was right," admits the Guinean international. But, rather than looking to quit and move on for pastures new, he says he will fight on.
"I think he expected a lot of me, but I signed for three years and I will do everything to show the public here that I was a good choice - and next year I will show what I am capable of on the pitch.
"I will have a holiday and be fresh for next season. I would have preferred to have played the games at the end of the season as they are the important ones, and I am really sorry about that.
"Perhaps the supporters were expecting a lot from myself but it's true that it wasn't easy to quit a club like Liverpool and adapt to life in London, and the way of playing.
"It was a new system, new players, and it obviously wasn't working - you need time.
"Some players take longer than others, and I thought it would be easy when I came.
"It is up to me to prove next season that I merit a place in the West Ham side, and if I am in good health I think I can deliver. I will attack the new season and give it 200%."
Titi missed games since signing from Liverpool for £1.5m through a combination of loss of form and injury. A knee operation was eventually required which may yet impinge on his preseason training.
But he feels that with a new manager he can have a fresh start, and adds: "Everyone would have liked Harry to remain and it's thanks to him that I am here, but that's the nature of the job.
"The club and the team remain and it is up to us to get going for the new season.
"Next season we will all be equal and everyone will have to prove their value."
