Soccer: Everton can 'change everything' during busy Christmas - Sigurdsson

(Reuters) - Everton can completely transform their season by getting positive results during a packed Christmas period, midfielder Gylfi Sigurdsson has said.

The resurgent Merseyside club have climbed out of the bottom half of the Premier League and into ninth position with three wins and a draw in four games since Sam Allardyce's appointment as manager earlier this month.

Everton will play four league games and an FA Cup fixture against Liverpool over the next two weeks and Iceland international Sigurdsson has backed the team to continue their revival during a tough period.

"It was a very tough and slow start to the season but at the moment things are looking a lot better. We still need to improve on a few things to keep the momentum going heading into this busy Christmas period," Sigurdsson told the club's website. (www.evertonfc.com)

"A few good results change everything in this league and now we're looking forward to a lot of games over Christmas and we can turn this season completely around."

Everton host Chelsea at Goodison Park on Saturday and Sigurdsson called for a competent all-round performance against the champions.

"Chelsea are a very good team and we're going to have to perform really well and make sure we take our chances as defensively they are very good and not too bad going forward, either!," the 28-year-old added.

"It's going to be a tough game but over the past few weeks we've been getting good results so we'd like to build on that."
