en Foster believes the Birmingham fans "deserve answers" about the club's future after completing his season-long loan move to West Brom.[LNB] Foster helped Blues win the Carling Cup six months ago via a shock win over Arsenal at Wembley but has witnessed the dramatic slump in fortunes since with sadness.[LNB]City were relegated from the Premier League, saw manager Alex McLeish and more than a dozen players leave and leading share-holder Carson Yeung charged with alleged money-laundering in Hong Kong.[LNB]It has left the supporters worried about what lies ahead and Foster believes they need to be put in the picture.[LNB]He said: "It is a big shame. I made no secret of how much I enjoyed it last season.[LNB]"Everything was so good at Birmingham. The fans were fantastic and there were some very big highs and very big lows at the end of the season.[LNB]"I've got a lot of friends within the club, not just the players but the staff as well, masseurs, physios, people like that.[LNB]"It is not only the players that have to be sold when relegation happens. It is people like that which lose their jobs as well which makes it quite sad as well."[LNB]Foster added: "Am I worried about the future of Birmingham? It is something that a lot of the fans are worried about. They need answers.[LNB]"They've been there for the club through thick and thin and the thing that is worrying is that there are not too many answers coming out.[LNB]"They (the club) just need to answer things to put the fans minds at ease."[LNB]Foster noticed how the effect of relegation had quickly swept through the club when he reported back for pre-season training.[LNB]He said: "In pre-season there was something like 12-15 players from last season who had already left.[LNB]"It was a massive change and one thing that comes along with relegation. It was very sad.[LNB]"Obviously the debts haven't helped. You see other teams like West Ham and Blackpool go down but they are in a lot more different situation.[LNB]"They have held on to some of their star players. Unfortunately it wasn't possible at Blues.[LNB]"I am a little bit worried for the club. I don't know all the facts to be perfectly honest. I don't think anyone really does.[LNB]"We are going to have to wait and see and hopefully it will all clear up."[LNB]Foster admits the move to West Brom was ideal in not disrupting his family life.[LNB]He said: "It was ideal in the fact I've not got to uproot. I've got a young family now.[LNB]"It is something I find very important, that I've not got to move half-way across the country and ship them about.[LNB]"I can live from home and commute like I do every day. Once I got here, I realised what a nice and well run club it is."[LNB]Foster temporarily retired from international football at the end of last season and is maintaining the same stance with England for the time being.[LNB]He said: "I haven't had a rethink at all. I found last season when I was just concentrating on playing football for Birmingham, that I seemed to get my best form out of me.[LNB]"I haven't re-thought it at all and am concentrating on playing club-level football."[LNB]Midfielder Zoltan Gera has rejoined Albion on a two-year deal - with an extra year's option - and admits being reunited with Roy Hodgson was a big factor.[LNB]Hodgson signed the Hungary international from the Hawthorns when in charge at Fulham three years ago.[LNB]Gera said: "I was quite happy here when I was here for four years. But Roy was a big part for me to coming back to this club.[LNB]"For me it was the perfect combination, West Brom and Roy. I can't ask any better."[LNB]Gera will miss the opening three games of the season through suspension after being sent off for the Cottagers in the final game of last season.[LNB]But he expects to be available for the clash with Norwich on September 11 as he steps up his fitness programme following ankle surgery.
