Liverpool captain Jordan Henderson has admitted that his side need to improve defensively if they are to challenge for honours this season.

The Reds made a winning start to their campaign against Arsenal on Sunday, with goals from Philippe Coutinho (2), Adam Lallana and Sadio Mane helping them to a thrilling 4-3 victory.

Henderson acknowledged his side's attacking prowess, but warned that they will need to be tighter at the back going into this weekend's match against Burnley.

"It was a good win for us and of course we would have taken that before the game. We've got to be pleased with the three points but we know there are things we need to improve on before the weekend. In the first half we didn't play as well as we would have liked. We just didn't get going until after they scored," he told the Liverpool Echo.

"The last 10 to 15 minutes of the first half were better from us as we kept the ball better and then Philippe came up with the goods to get us level with that free kick. It was a big goal - an unbelievable strike. From there we grew into the game and looked a lot more confident. The manager spoke at half time about the things we needed to do better and I felt like we did that in the second half.

"We have got a lot of talented players going forward. We looked very dangerous at times. There's a lot of pace and creativity in the final third. We scored some great goals but we also need to be solid defensively and provide better protection. When Arsenal scored their second they gained momentum and we sat back a bit too much, inviting pressure, so that's something we need to work on.

"In the end we saw the game out and got the three points which was very pleasing but we all know we can do better. Burnley will be a different test and a tough test. We need to keep working and keep building as a team."

Liverpool conceded 50 league goals last season - the joint-most they have ever conceded in a 38-match Premier League campaign.
