Carroll has had a stop-start campaign to date, with injury halting his progress.
The England international striker has also had to deal with the added competition for places at Upton Park, with a number of attackers seemingly jumping ahead of him in the pecking order.
However, the 27-year-old was handed a start for West Ham against Manchester United in the FA Cup last Saturday.
And he said: “It was great [to start]. I’ve been working hard. I’ve been coming off the bench and it’s been hard not starting when I want to be but I was in and I think I got about 80 minutes, so it was great.
“[The selection choice available] is a great problem for the manager to have. We all have to keep trying and working to our best in training to be part of the starting XI.”
Carroll helped West Ham pick up a 1-1 draw against Manchester United at Old Trafford.
The target man striker had one real opening to score, but he headed over the bar from 12 yards.
Carroll will now be hoping to keep his place in West Ham’s line-up, but he faces a fight with the likes of Diafra Sakho, Enner Valencia and Emmanuel Emenike all battling for a spot in Slaven Bilic’s side.
Carroll has made seven starts in the Premier League so far this season, scoring three times.
