Former Arsenal and England defender Martin Keown says Gary Cahill should partner Chelsea skipper John Terry for their trip to Benfica.

David Luiz is also available for the Champions League quarterfinal.

But Keown told the Daily Mail: "I'd go with Cahill as he and Terry are starting to develop a good partnership. Luiz is a great talent but he is very erratic and it doesn't seem like defending is at the top of his list.

"Also, how can you drop Cahill after his match-saving performance against Tottenham and his goals in the previous two matches?"
