Chelsea goalkeeper Petr Cech has questioned whether Newcastle United will freeze tomorrow night.
Cech began the mind games ahead of Wednesday's clash by pointing out the Magpies' players were in uncharted territory.
He said: "I think our greater experience will be really important on Wednesday because Newcastle are in a position they haven't been in for a long time, only once maybe, and we have been there many times.
"It could be the decisive factor but they and we have everything to play for. It will be an exciting game but our experience will help."
