Frank Lampard hopes Callum Hudson-Odoi signs new Chelsea contract

"It's really very unsafe for injuries", Sarri told reporters.

And Sarri, who has used the England global sparingly so far this season, hailed the impact of the attacking midfielder. "He has been able to train after the problem with the back".

Meanwhile, Hudson-Odoi will hope to start at the expense of Pedro on the opposite wing while Ruben Loftus-Cheek is in contention for a midfield berth. He had a wonderful match and I'm really happy he could play for 90 minutes. Physically, technically and tactically he is improving.

Hudson-Odoi continued his eye-catching Europa League campaign with a goal and an assist at the Olympic Stadium, and Sarri was encouraged by the 18-year-old's display - while sounding a familiar note of caution. His nine goals make up an impressive 36% of goals scored by the Blues in the Europa League, having scored them all in his last seven appearances.

"Recently, every time he has been on the pitch, he has played really very well", he later told a media conference.

"I prefer to find them in the final", Chelsea's head coach said when informed that Napoli had also qualified.

The last time the Blues were in the Europa League was in 2013, when they went on to win it in a dramatic 2-1 final win over Benfica.

'And second, it means that Naples are in the final, and I am happy.

Two more goals for Chelsea before half-time - Giroud's second and a sliding finish from Marcos Alonso from a Callum Hudson-Odoi cross - put the tie to bed for Maurizio Sarri's side with 45 minutes left to play. "I'm happy for him, but he has to keep the feet on the ground because he can improve more".

'You know very well my relationship with the city, with the people. "So, for me, it will be very hard to play against them in Naples".
