Martin Keown has warned Mikel Arteta that he could soon have a big problem on his hands with Kieran Tierney - a player he tipped as a "future Arsenal captain" less than 12 months ago.
Tierney has quickly become a fan-favourite at the Emirates Stadium after joining the Gunners from Celtic in a £25million deal back in 2019. But the Scottish full-back, who impressed in Thursday night's 3-0 win over FK Bodo/Glimt, has fallen behind new boy Oleksandr Zinchenko in the pecking order.
Although Zinchenko was tipped to feature in a midfield role after leaving Manchester City, the Ukrainian ace has made the left-back berth his own ahead of Tierney.
