Newcastle United's Rolando Aarons looks a hugely exciting prospect for both club and country, but his first season in senior football has exposed a concern about his future.
Aarons has been one of the positives to come out of what has been a disappointing season for Newcastle, but there must be a worry about his persistent injuries.
The winger has had to spend regular time on the sidelines and the hope will be that he will not be another player who finds his career blighted by injury.
Aarons has made just five appearances for the Magpies this term, with his progress severely hampered by a set of injury problems.
Every time the 19-year-old has looked close to a return he has faced a set-back and it must, therefore, be a worry that he seems so prone to injury.
Although Aarons is still young and the hope is that he will grow out of these fitness issues, his tendency to pick them up at such a crucial stage of his career will unquestionably have negatively impacted his development.
Aarons could easily have been into double-figures for appearances this campaign had he stayed fit and that first-team experience is key to someone just starting out.
Instead, he has missed out due to his prolonged time on the sidelines and it the could cost him over the long term.
The hope for Magpies supporters are that these injuries are just teething problems and not a sign of things to come, as if Aarons can stay off the treatment table he looks set to play a vital part in the first-team for the years to come.
