Jurgen Klopp allowed a bit of Christmas cheer into Liverpool's training session at Melwood on Wednesday night.

The Liverpool squad were pictured beaming in festive Santa hats as they took a break from their preparations for Friday night's clash with Arsenal.

After returning to winning ways in emphatic style at Bournemouth at the weekend, Klopp will want his side to send down a marker as the busy schedule hots up over the holiday season.

Liverpool play four times in 11 days over the Christmas period as the Premier League approaches its busiest point of the campaign. 

The Reds host Swansea on Boxing Day and Leicester four days later before going to Burnley on New Year's Day.

Everton are then the opponents at Anfield in the third round of the FA Cup on January 5 - another Friday night match.

Klopp will be looking to rotate his squad over the next fortnight, with Alex Oxlade-Chamberlain in line to face his former club later this week.

The midfielder has gradually improved since a tough start, claiming the man of the match in the 4-0 win at the Vitality Stadium on Sunday.

And Klopp believes there is still much more to come from him - particularly in front of goal.

'I think the biggest improvement and potential is being involved in goal scoring situations', the German said.

'It is unbelievable but he was not asked for this too much in the past.

'If you watch Arsenal in the past the past their two decisive players were Mesut Ozil and Alexis Sanchez. They are involved in a lot of moments and decisive passes. Always Ozil or Sanchez.

'So then you are not much involved. Then Olivier Giroud when he is coming on the pitch.

'Here we put it on more shoulders, much more shoulders. If Alex is on the pitch he needs to be involved in these situations. At the moment I am fine. It's all good.

'There is a lot of space for improvement as well. It's all good.'
