John Terry has warned some senior Chelsea players that tonight's Champions League match against Napoli could be their last chance to play in the competition.
The Blues go into tonight's last-16 clash trailing the Italian club 3-1 from the first leg.
"I think this could be the last chance for this group of players in Europe," Terry said.
"We have players who are out of contract in the summer and others who are in negotiation over their current deals.
"I am hoping that many of them stay and many more come in, but the key factor when it comes to new signings is that we need to be playing Champions League football next year."
A Napoli win tonight means that there would be no English team in the Champions League quarter-finals for the first time since 1996.
