Mertesacker explains why signing Luiz was a good decision
- Arsenal signed the Brazilian on deadline day.
- The 32-year-old made a couple of mistakes already.
- However, the academy director believes the centre-back will only grow stronger.
Speaking with Sky Sports, Per Mertesacker dwelled on the unexpected signing of David Luiz and why the Brazilian can be a success at the Emirates.
"I think he [David Luiz] will learn from his mistakes on the pitch, but he is very comfortable being at Arsenal.
"That's what I have been seeing. So we are happy to have him.
"He brings something different to the table right now. So I think he is able to learn and excel his level of being an Arsenal player."
