Olivier Giroud's second-half goal ensured Arsenal's return to the top of the Premier League on Sunday.
Giroud's 11th goal of the season sealed Arsenal's return to the top after a hard-fought 1-0 win at Newcastle.
Arsene Wenger's side had surrendered first place after Manchester City's win over Crystal Palace on Saturday, sports 24 reports.
However, 24 hours after the Gunners reclaimed pole position with a hard-fought victory at St James' Park.
Arsenal, who were without German playmaker Mesut Ozil, were under pressure and Wojciech Szczesny had to tip over Moussa Sissoko's effort.
But France forward Giroud bagged his 11th goal of the season with a glancing header from Theo Walcott's free-kick in the 65th minute, the report added.
