West Ham forward Ricardo Vaz Te has expressed his disappointment after missing a gilt-edged opportunity to equalise during the Hammers' 1-0 Premier League defeat to Reading on Saturday.
The winger was unable to convert what his manager Sam Allardyce described as "the easiest chance you'll ever see in a Premier League football match" from Matt Jarvis' cross.
Vaz Te was making his return from a dislocated shoulder at the Madejski Stadium and hopes he can make amends in the coming weeks.
"I'm just very disappointed with the result, especially after coming on and having a great chance to score," he told the club's official website. "I felt like I should have done better and I should have scored. There was no excuse for that.
"I'm just really disappointed I couldn't make it for the lads, really. I felt like I let everybody down and I'm just going to try to do better next time. I'm glad to be back and I want to regain my place again."
Vaz Te has been sidelined for ten weeks by the shoulder problem, with his substitute appearance coming two weeks ahead of schedule.
The former Barnsley player believes that he is still far from full match fitness after playing for the final twenty minutes in Berkshire.
"I'm not sure I am ready to start yet," he admitted. "I have only trained the past week and I didn't play any games before.
"I played for 20 minutes at Reading and it was quite hard, so I'm just going to keep training to get my fitness as quick as possible."
He added: "I will do my best if the gaffer decides to put me on [against Norwich on January 1]. Personally, I don't think I'm ready to start a game but if that's the gaffer's choice I will always do my best, like I said."
