With just over a week before his scheduled return to the United States, David Beckham says he is becoming frustrated by the delay in his possible transfer to Italy's AC Milan. The clubs remained at a stalemate in transfer negotiations on Thursday. Beckham's loan to Milan from the Los Angeles Galaxy ends on March 8. Milan offered $3 million, but Los Angeles said it wanted at least $10 million. Milan vice president Adriano Galliani responded by saying that the club was not prepared to go any higher for a 33-year-old who will become a free agent in November. “Of course (it is frustrating),” Beckham said after Milan's exit from the UEFA Cup. “There's a lot going on and a lot being said and every day someone is asking me questions about what's happening. “It needn't be said every day, but so far I am trying to concentrate on the football. At the moment we'll have to see what happens. At the moment it is being discussed and negotiated.” Beckham played the full 90 minutes for Milan. They raced into a 2-0 lead by halftime, but defensive tactics in the second half allowed Bremen to score twice and the German club progressed on away goals after the series finished 3-3 on aggregate. Beckham said dropping out of the UEFA Cup didn't affect his desire to stay with Milan. “It doesn't change me wanting to play at this club and hopefully it doesn't change other people's views of me wanting to stay at this club.” Extra refs FIFA's lawmakers meet on Saturday to discuss changes to soccer's rulebook including extra referees, sin-bins for yellow card offences and increasing the number of substitutions during a match. The International Football Association Board (IFAB) – which sets the rules for the world's most popular sport – will assess whether extra linesmen monitoring penalty areas at the end of each pitch can help alert referees to fouls or diving, while avoiding the need to introduce potentially disruptive video replays. European governing body UEFA will deliver the results of its recent trials at under-age tournaments and international matches in Slovenia, Cyprus and Hungary. UEFA chief Michel Platini and FIFA president Sepp Blatter both favor such an approach instead of video replays like those used in rugby when the referee is unsure whether a try has been scored. The game's top officials say such television replays hamper the fluidity of a match with unnecessary stoppages. But the IFAB – made up of the four British associations and four representatives from FIFA – will look at the merits of introducing rugby's sin-bin whereby a player booked for a foul is sent to sit on the sidelines for a set amount of time.
