Kieran Tierney is being closely managed by Real Sociedad as they look to monitor his workload, according to a report. The Scotland international joined the La Liga side in the final throws of the summer transfer window on a season-long loan from Arsenal.
He's been thrown straight into the deep end at the Basque club, with a strong performance away at Real Madrid before an hour of action in a 1-1 draw in the Champions League with Inter Milan.
But it is coming at a physical cost though to the Arsenal loanee. Mundo Deportivo claim the Celtic hero "showed signs of some discomfort on Wednesday" and "asked for a change" against Inter after a rapid start to life in Spain.
He has also missed training ahead of a return to La Liga action against Getafe at the weekend, alongside Martin Zubimendi and Arsen Zakharyan.
