Chelsea are interested in Atletico Madrid midfielder Thomas Partey.

Partey has been a top target for Arsenal, who are desperate to sign a new defensive midfielder so that Mikel Arteta can play 4-3-3 instead of the 3-4-3 formation he has been deploying.

But Blues manager Frank Lampard is also in need of reinforcements - and his defensive situation continues to become more confusing when you consider he is reportedly willing to sell Antonio Rudiger.

Chelsea have plenty of back-up in midfield either way, but could be in trouble if N'Golo Kante is injured.

The Guardian says Partey is a viable alternative before Monday night's transfer deadline.

Arsenal have chosen to prioritise their pursuit of Lyon midfielder Houssem Aouar, but have so far struggled to make a breakthrough.
