David Luiz has fired a dig at Unai Emery

David Luiz has fired a dig at Unai Emery by admitting that Mikel Arteta has brought happiness back to

Arsenal after their victory over Manchester United on New Year’s Day.

First-half goals from Nicolas Pepe and Sokratis Papastathopoulos sealed a 2-0 win over Ole Gunnar Solskjaer and a first victory for Arteta since he was appointed last month.

Emery was sacked while Arsenal were on a run of just one win in 11 games, while that record was extended to 15 matches following the 2-1 defeat to Chelsea last Sunday.

But Luiz insists Arteta has restored confidence following his arrival and believes the mood among the squad during Emery’s reign played a major part in their poor run of form.

‘We have to be honest and admit physically we are not ready, but you have to show heart and this team is ready to change a lot of things,’ Luiz told BT Sport after Arsenal’s win over Manchester United.

‘We showed that today and we are going to do big things in the future but step by step.

‘Mikel Arteta is a great coach, he knows football, he was a great player.

‘He brings things and I believe in his philosophy. I think he can improve every single player.

‘In life when you are happy the results can be totally different.
