Noel Whelan has urged Everton to sign Sidibe on a permanent deal at the end of this season.
The defender is currently on loan at the club and the Toffees have the option to make it a permanent deal for a fee of around £12m.
The 27-year-old Frenchman has done well so far in the Premier League and Whelan believes that he can be a useful player for Ancelotti next season.
The pundit claims that Sidibe has shown that he is capable of succeeding in the Premier League and he has the right attitude.
