Dejan Kulusevski is an injury doubt for the north London derby on Saturday after picking up a hamstring problem while on international duty with Sweden.
The Tottenham forward has been a big hit in the Premier League since signing from Juventus in January, contributing a goal and three assists in domestic action so far this season, though he has been rotated with summer signing Richarlison in recent times.
However, after playing in both Nations League games for his country over the international break, The Athletic say he is being monitored by medical staff at Hotspur Way but is facing a battle to be fit in time.
Manager Antonio Conte is expected to give an injury update during his press conference on Thursday, though he now has strength in depth if Kulusevski cannot make it in time for the clash at the Emirates.
Son Heung-min returned to form with a hat trick off the bench against Leicester and scored a free-kick recently for the Korea Republic, while Richarlison netted three goals and contributed an assist in Brazil's victories over Ghana and Tunisia.
Hugo Lloris will need a late call on his fitness after pulling out of France duty and Spurs will be hoping their captain can retain his spot between the sticks. If not, Fraser Forster is expected to make his debut.
Ben Davies is also a doubt so Clement Lenglet will likely continue in the back three, while Lucas Moura may miss out on the squad altogether.
