David Luiz trained separately from Chelsea's first team with Arsenal pushing to sign the defender

The 32-year-old was at Chelsea's Cobham training ground, but it is understood he did not take part in the main training session with Frank Lampard's men.

Luiz signed a new two-year contract in May, with Chelsea straying from their standard practice of handing one-year extensions to players aged 30 or older.

Arsenal boss Unai Emery is expected to push to lure Luiz away from Stamford Bridge before the transfer window shuts at 5pm on Thursday.

New Chelsea boss Lampard preferred Kurt Zouma and Andreas Christensen for his centre-back pairing in the final pre-season friendly at Borussia Monchengladbach last weekend.

Lampard has brought Zouma back into the first-team fold after the 24-year-old France defender spent last term on loan at Everton.

Luiz enjoyed a central role under Maurizio Sarri last season, as Chelsea secured a third-place Premier League finish and lifted the Europa League title.

But now Zouma and Christensen could be in line to pair up for Sunday's trip to Manchester United in Chelsea's opening league fixture.
