Promising attack-minded Arsenal midfielder Serge Gnabry, 19, needed no second invitation to get his feet stuck firmly into full senior-level training at London Colney earlier today, Monday.
And the German's presence at Gunners HQ has pleased centre back and World Cup champion Per Mertesacker.
The towering defender said that the Arsenal stars who were on international duty "were missed at training today" before replying to a tweet sent by Gnabry.
"[I'm] back in full training with the team after a long recovery - always stay positive," said Serge.
To which Mertesacker said: "Good you are back!"
Gnabry is the same age as Raheem Sterling but, last year, was only subjected to cameo appearances, while the Liverpool attacker began to establish himself as a first choice player.
If entrusted with increased playing time, could Gnabry go on to have as big an impact as Sterling had last season?
In 2013/14 Premier League duty, Gnabry was selected to start on five occasions (four as a substitute).
During those 470 minutes of competitive football, Gnabry returned an 85% passing accuracy, provided six key passes, embarked on 12 successful dribbls and returned one goal from 12 shots.
