Speculation continues to linger around the future of golazo-scoring forward Lukas Podolski, 28.
The German international has only played 902 minutes of Premier League football this season, made just one outing in the Champions League and appears out of favour with manager Arsene Wenger when it comes to the centre forward role.
In the past 12 months he has also been linked with a plethora of elite-level continental clubs including Galatasaray (The Express, last summer), Borussia Dortmund and Atletico Madrid (The Sun, last summer) and, most recently, Internazionale (Daily Star, Metro and The Sun, March).
It would be a transfer back to the Bundesliga that may interest Podolski, most, though, as he is reported by transfermarkt's World Cup issue to have said: "The Bundesliga is one of the best leagues in the world and therefore in principle always interesting.
"In the Bundesliga, I naturally think first of the FC [Cologne]. That is much more than a club for me, this is home. Maybe I'm playing again with the Billy Goats, this is for me always an option and heart."
If Wenger were to sanction an exit for Podolski, would it be his biggest mistake this summer?
Statistically speaking, he is the Gunners' most impressive goal-scorer despite the fact Olivier Giroud has played over three times as much football in Premier League competition.
Out of all of Arsenal's recognised strikers, Podolski has the best shots on target (SoT) ratio, returns a goal with 28% of his shots (proof of a: his accuracy and b: his ability to capitalise on whatever chances he is afforded, particularly when compared to Giroud) and is also responsible for either scoring or setting up a goal once every 90.2 minutes - far superior to Giroud's attacking efficiency of a goal or assist every 134 minutes.
