"Nothing at the moment, so we have put him in the squad", Southgate told a news conference after unveiling his squad at their St George's Park training base in Burton, central England. "Our hope, obviously, is that common sense prevails and that he is available for our matches, but we have to wait and see on that".
"So we have had a good conversation with the club, but more importantly for me was the conversation I had with him. We hope to have him available".
Wenger praises Wilshere's 'outstanding' contribution as Arsenal beat BATE
Arsenal conceded two goals, as Mirko Ivanic and Mikhail Gordeichuk bagged for the hosts, and did not look convincing at the back. The Walcott opened the scoring after nine minutes with a volley from close range, after some good work by Jack Wilshere .
Even if Alli can not play next week, Southgate wants to keep the Spurs man integrated in his squad given his status as one of England's key players.
Nathaniel Chalobah, Danny Welbeck and Tom Heaton - members of the last squad - also miss out through injury.
Southampton keeper Fraser Forster joined Delph as the only changes to the squad, with Everton's Michael Keane also included despite concerns over a foot complaint.
Fellow striker Jamie Vardy was not included in the squad as he recovers from a hip injury and Southgate said that the 30-year-old had been playing through pain and would benefit from a rest during the two-week global break.
