Arsenal are ready to start negotiations with Valencia to sign goalkeeper Vicente Guaita. An Arsenal representative will travel to Spain on Tuesday to try and sort a deal for the 26-year-old who is unsettled after he was left out Valencia's starting line-up for their 1-0 win against Malaga last weekend. The La Liga side are keen to extend his contract - his current deal expires in 2015 - and have no desire to sell him.
