Arsenal defensive crisis could force Ljungberg to call up teen Zech Medley after Saka replaces crocked Kolasinac

ARSENAL'S defensive crisis hit rock bottom after Sead Kolasinac became their THIRD full back to be injured in the last week.

And it means struggling stand-in boss Freddie Ljungberg could be forced to turn to teenager Zech Medley after winger Bukayo Saka had to replace Kolasinac.

Left back Kolasinac was forced off after 38 minutes of the Gunners' clash against Man City at the Emirates.

The Bosnian now joins Kieran Tierney and Hector Bellerin on the sidelines.

City raced into a 3-0 lead at half-time after two goals from Kevin De Bruyne and another from Raheem Sterling piled more misery on Ljungberg.

And it looks like the temporary boss could be forced to go down into his Under-23s to find a suitable replacement.

Medley, 19, arrived from Chelsea midway through the 2016-17 season.

And the Gunners' official website says he "has shown his quality as a full back and is capable of driving forward into the midfield" - despite mainly being used as a centre-back.

Medley, who is from Greenwich in Greater London, was an unused sub in Arsenal's Europa League 2-2 draw against Standard Liege earlier this week.

The 6ft 5in defender has started three games for Arsenal in the Premier League 2 this season and made one appearance from the bench, scoring in the 3-1 win over Blackburn last week.

And prior to that he was captain of the Under-18s where he won praise for his "commanding performances".

Medley made his senior debut for Arsenal in November 2018 when he came on as a sub for Rob Holding in the Europa League clash against Vorska Poltava.
