Arsenal agree £8m deal with Chelsea to sign David Luiz

Arsenal have agreed a deal to sign Chelsea defender David Luiz for a fee of around £8million.

The Brazilian refused to train on Thursday as he looked to force through a shock move to the Emirates.

The move has seemingly come out of nowhere but Arsenal widened their search for a centre-back following the departure of Laurent Koscielny to Bordeaux.

Chelsea are currently serving a two-window transfer ban and it was thought unlikely that the Blues would sanction Luiz's departure, especially to a top four rival.

However, the Mirror claim that a fee of £8m has been agreed between the two parties and that Luiz will undergo a medical in north London today.

The deal is a huge coup for Unai Emery, who worked with the Brazilian when he was at PSG.

The Spaniard admires Luiz's ability on the ball and he believes he has at least another two years at the top.

Luiz will sign a deal with the Gunners until 2021, replicating the extension he signed at Chelsea just three months ago.

Arsenal also hope to sign Celtic ace Kieran Tierney today after settling on a £25m fee.
