Joe Ledley claims Celtic not making Champions League last 16 would be 'unthinkable'

Joe Ledley reckons it would be "unthinkable" for Celtic not to reach the knockout stages after their heroics against Barcelona.

Desperate

The Wales international realises that will not be a straightforward task against the Russian side but admits the players are desperate to finish off the job. "We know it will be difficult against Spartak," added Ledley. "We had a fantastic result against them in Russia but they are a still a great team. "They have nothing to play for now, they are out so the pressure is off them and I don't know how that will affect how they play against us. "Our focus is only on Celtic and how we perform and if we give our all we can secure the win. "We will be going all out to get the result we need to qualify for the last 16. We have come all this way and now we are all desperate to finish the job off. "If we look back at the Benfica game then, in the cold light of day we will realise we didn't create as many chances as we had hoped. "But we have to be fair on ourselves too because we knew the Stadium of Light was always going to be a difficult place to go and get a result. "And we defended magnificently again as a team and as a unit. Everyone put their bodies on the line for the cause but what cost us at the end was switching off." "Concentration is key at this level and unfortunately ours let us down towards the end and it proved costly. "Even still, we had a couple of late chances and we might have grabbed an equaliser that would have taken us through to the knockout stage already. "That only goes to show how fine the margins are at this level."
