Arsenal are weighing up a £35million double raid on Swansea for striker Michu and defender Ashley Williams as the club look to respond to mounting criticism over their lack of signings. Saturday’s 3-1 home defeat to Aston Villa provoked an angry response from supporters who booed the team off at the final whistle and chanted “spend some f*****g” money to manager Arsene Wenger. The Gunners have only signed 20-year-old striker Yaya Sanogo having been frustrated in their pursuits of a number of leading players including Gonzalo Higuain Luis Suarez Luiz Gustavo and Wayne Rooney. The Arsenal Supporters’ Trust last night called for the suspension of talks over an extension to Wenger’s contract — which expires in the summer — claiming “this is inappropriate” with the transfer window open until September 2. Wenger has admitted he wants “two or three” signings and is now considering moving for a couple of players he has tracked for some time. Michu enjoyed a hugely successful first season in English football scoring 22 goals. It is understood that Swansea are reluctant to sell but have valued the 27-year-old at £25m in the knowledge that a bid at that level would be hard to reject especially with Michael Laudrup still keen to add to his squad.
