The race to sign World Cup winner Sami Khedira took another twist today as Chelsea leapfrogged Arsenal as favourites to sign the Real Madrid midfielder. The Gunners were trying to make Khedira their second major signing of the summer following the capture of Alexis Sanchez, but are now on the brink of missing out to their London rivals. With just 12 months left on his contract at Real, Madrid officials have made it clear that Khedira can leave the Bernabeu this summer, which has led to the two-way shootout between Chelsea and Arsenal for his services. Just yesterday the 27-year-old looked destined for the Emirates, but now it looks like he could instead wind up at Stamford Bridge and break Gunners hearts. The Gunners are reportedly reluctant to meet Khediras wage demands, meaning the notoriously-frugal Arsene Wenger is facing the very real prospect of missing out on another big target if he doesnt dig deep enough into his pockets and splash the cash. But it isnt just money that concerns Khediras next big career move, and the midfielder has some important decisions to make just days after winning the World Cup with Germany. Here, we take a look at 5 reasons why hed be right to pick Chelsea.
