Chelsea's interim coach Guus Hiddink is already working on a way to combat Barcelona's attacking prowess without a recognised left-back.
Ashley Cole's second-half booking in last night's astonishing 4-4 draw with Liverpool has left the Blues with a real headache when Chelsea meet the Spanish giants in the first leg of their Champions League semi-final at the Nou Camp in a fortnight.
The club's decision to sell Wayne Bridge to Manchester City in the January transfer window and Paulo Ferreira's subsequent knee ligament injury have conspired, along with Cole's booking, to leave Hiddink searching within his ranks for a player capable of stopping Barcelona's Lionel Messi.
'The left-back situation might cause problems but we have time to think how we might resolve it,' said Hiddink.
'Barcelona are a very advanced team with very skilful players. They know how to handle the pace. I like their philosophy of football.
