Germany's Shkodran Mustafi celebrates with teammates
The London Evening Standard are reporting that City defender Eliaquim Mangala is available for transfer following Guardiola's big money move, and that Valencia are particularly interested in his services, amid ongoing reports that Mustafi is set for a switch to the Emirates.

With the manner in which big money moves have occurred this summer, it wouldn't be a surprise if Valencia sanction the departure of their defender once a deal for Mangala was agreed.
Arsenal are reportedly chasing 24-year-old Mustafi, with the Mail suggesting a £30 million bid will be made to convince the La Liga side to sell, and the availability of a high-profile replacement such as Mangala would likely leave Los Che more open to business.
The Frenchman's playing time at the Etihad, already far from certain before the England international completed his move, looks almost non-existent now Stones has joined.

Mangala was one of Manuel Pellegrini's major signings during his second summer at City, having just won the Premier League in the Chilean's debut season in Manchester. But the defender failed to ever convince in the English top flight, often finding it hard to keep his composure and positional sense in a league certainly more non-stop than he would have experienced in Belgium or Portugal.
It looks like City paid significantly over the odds when they brought him to England, and Valencia would be hoping to sign the 25-year-old at a fee much less than the £32 million (Independent) it cost to sign him from Porto.
Arsenal have the opposite problem to a City squad with too many international defenders, with big injury problems in central defence heading into the start of the Premier League season meaning they are in desperate need of reinforcements.
Mangala's availability may not mean a move for Mustafi can get done in time for the game against Liverpool, but the sooner the former Sampdoria man arrives the better, and Mangala may have an important role in that.
