Liverpool manager Jurgen Klopp believes his side's thrilling draw with Arsenal has shown how good they can be but insisted defensive organisation and a lack of players available to him and remains a problem.

Liverpool took the lead twice in the first half through goals from Roberto Firmino – the second a stunning effort from outside the box – but Aaron Ramsey and Olivier Giroud twice wiped out their advantage.

Arsenal looked like they would be returning to north London with all three points after Giroud scored his second 10 minutes into the second half only for Joe Allen to come off the bench and draw the game level at 3-3 in the final minute of normal time.

"We started so good and played so good football. It showed all of us how good we could be," Klopp told BT Sport post-match.

"Then we concede a goal from a set play and we have to work at it. Organisation is one thing and sometimes we have a little problem with concentration.

"We gave them two easy goals after we had to work really hard for our goals. We had many moments which I am happy with.

"At 3-2, both teams had a low battery. We scored with a perfect pass, perfect header, perfect finish and nobody doubts it was deserved.

"I have no problem with the number of games, the problem is we don't have enough players for the number of games."

While Kolo Toure and Mamadou Sakho were fit again to provide Klopp options at centre half, Liverpool are still without eight members of their first team squad with Divock Origi, Philippe Coutinho, Dejan Lovren, Martin Skrtel, Jordan Rossiter and Daniel Sturridge all nursing respective knocks with Danny Ings and Joe Gomez long-term absentees.

Liverpool host arch-rivals Manchester United at Anfield on Sunday 17 January.
