3 Chelsea players who must try and impress against Sheffield United in the Premier League

3. Mateo Kovacic 

With so many midfielders to choose from Kovacic has struggled for regular game time this season. However, boss Lampard was keen to keep the Croatia international in his playing squad and we believe the box-to-box midfielder will start on Saturday. The talented, tidy player will be very keen to impress his manager and hope his performance will lead to more opportunities from the start.
