The Brazilian playmaker has only made a handful of appearances for the Blues since joining the London club from Sao Paolo in 2011, and is currently away from Stamford Bridge on loan at Eintracht Frankfurt.
Piazon is one of over 20 players currently away from Chelsea on a temporary basis, with Jose Mourinho’s side using such rulings to farm out fringe players for development purposes.
Although the silky passer has revealed that he wants to impress his boss ahead of a potential return next year, it looks unlikely at this stage that he will be able to compete with the likes of Eden Hazard, Oscar and Willian for a spot in the XI.
Yet his fine showings in Germany appear to have opened up English options, with Arsenal and Everton both monitoring his progress.
The duo are thought to be confident of snapping him up from Chelsea, who have shown by selling Romelu Lukaku that they’re willing to offload loanees to divisional rivals.
Piazon grabbed headlines a few weeks ago by netting a stunning free-kick for Frankfurt against Hamburg.
