The 28-year-old has been given little in the way of game time so far this season.
The circus surrounding Diego Costa has been plentiful this season.
Indeed, Costa has been given ample chances to impress, while the Spaniard's absence saw a false nine played against Tottenham Hotspur.
Mourinho, however, has a perfectly capable forward in Loic Remy waiting in the wings. He should use him against Leicester.

As Opta stats show, Remy has been given just 107 minutes of Premier League action so far this season. Ruben Loftus-Cheek has been criminally underused but even Radamel Falcao and Kenedy have more minutes under their belts than Remy.
So why not turn to the forward against Leicester? If the likes of Willian and Eden Hazard do their job, they'll flourish regardless of who's in front of them. And why not simply have someone who could perform their role ably up front?
Mourinho could argue he's given Remy his chance - but he hasn't. Six appearances in the Premier League spanning just 107 minutes is nothing, while Remy's fitness seems to have improved from last season.
Leicester's main threat will be Jamie Vardy running in behind - why not counter it with the same approach using a quicker, more mobile centre-forward?
