Britain face Liechtenstein in Group 1 Pool B on Wednesday followed by Turkey, before their clash with Ukraine on Friday.
They must win all three matches if they are to progress and Murray hopes the team ethic she has tried to build will reap dividends at this week???s event in Budapest.
???Our biggest challenge would be Ukraine who are led by Elina Svitolina,??? Murray told Sky Sports News HQ.
???She took Serena Williams to three sets at the Australian Open and is in very good form at the moment but we play them on the Friday so hopefully we will be well warmed up by then.
???But one of the most important things for me was to build a good team spirit so that the girls work together while we are on Fed Cup (duty) because one of the things about individual sport is that you don???t have that kind of team relationship.???
Guernsey-born Heather Watson will lead the British charge in Hungary this week. The 22-year-old won the Hobart International at the start of the year before her painful first round elimination at the Australian Open
???The year started well for me,??? Watson said. ???I wish the Australian Open could have gone a bit better but all in all it???s been a good trip to Australia.
???I love being involved in the Fed Cup. I???ve played in it every year that I can and I love being part of a team event.???
