Injury news: Arsenal ace ruled out of Spurs clash

Arsenal goalkeeper Petr Cech is doubtful for north London derby against Tottenham.

Cech, who limped off during the weekend win over Everton with a calf injury, was assessed by Gunners staff on Monday and Arsene Wenger will have to call upon understudy David Ospina  who has not made a single Premier League start this season.

The Colombia international has long been the recognized cup goalkeeper at the club and has featured in the Europa League, EFL Cup and FA Cup this season. But he has not made a league start for the Gunners since the 2-2 draw with Manchester City in April last year.

Since joining in the summer of 2014, the 29-year-old has made 23 Premier League appearances.
