The Arsenal midfielder enjoyed a fruitful loan spell at Upton Park last term and believes that with the quality at their disposal, the Hammers can survive next year
The England Under-21 international enjoyed a loan spell at Upton Park last season, featuring in 22 league games over the course of their promotion campaign and was impressed with the quality that he saw within the squad.
"There are some good players here and they all want to do well," Lansbury told West Ham's official website.
"People were talking about pressure and being favourites for the final and all of that, but that has been around all season.
"I think the lads can do well next year, there is no reason why not."
Lansbury also praised the Hammers' fans for perservering through a season in the second tier and believes they have now been rewarded with a day out at Wembley and a return to top-flight football.
"It is massive for the club obviously as it means being back in the Premier League. It is also massive for the West Ham fans," he continued.
"You know they would have made sure they had a good day out at Wembley whatever happened as it is such a great place to come to.
"But the fact that their team won means so much and we are all glad that this could happen for them as they deserve it. They have certainly been fantastic in my time here."
