Theo Walcott trained on his own on Monday afternoon as he nurses a hamstring problem which is likely to keep him out of the clash against Ludogorets on Tuesday evening, according to a report.

The forward was absent during Arsenal’s 4-1 victory over Sunderland on Saturday afternoon and isn’t expected to return until the Gunners face Tottenham next weekend.

Walcott carried out a separate training session as the rest of the Arsenal squad prepare for their Champions League game against Ludogorets, according to Goal.

Arsene Wenger’s side recorded a dominating 6-0 victory in Europe on their last outing against Ludogorets, with Walcott grabbing one of the goals.

The 27-year-old is still not fit enough to feature though and Arsenal will hope to see him return against Tottenham in Sunday’s north London derby.

Santi Cazorla and Nacho Monreal will also be missing from Arsenal’s squad, but Aaron Ramsey, Olivier Giroud and Granit Xhaka could all return to the starting XI.

Walcott has started nine games in the league this season and has scored five goals, with only teammate Alexis Sanchez, Romelu Lukaku, Diego Costa and Sergio Aguero scoring more in the Premier League.

In total, the Arsenal forward has netted eight goals in his last 11 appearances and would be a huge loss if he isn’t fully fit for the clash against Tottenham next Sunday.
