It is often folly to predict Arsene Wenger's next move. He is perhaps the most principled and unwavering manager in the Premier League, yet his motives and thought processes are often relatively well masked from the media and, as a result, the wider public.
What is clear, however, is that Wenger wants a new striker to add some depth to his squad—someone to alleviate the pressure on Olivier Giroud, Nicklas Bendtner and Lukas Podolski.
His interest in Real Madrid's Alvaro Morata betrayed his thought process. He wants an ideally young, physical presence whom he can use as a back-up to Giroud, allowing him to use Podolski more out wide and use Bendtner (who is currently injured) far less.
Arsenal could see out the season without adding another striker, but with the title tantalisingly within reach, the temptation to find what might be the missing piece will surely prove too hard to resist. The question, then, is whom they will find.
Morata appears to be out of the question, per Alex Richards of The Daily Mirror, while a return for Chelsea's Demba Ba (on loan) would seem likely to be as difficult as it proved in the summer (if only because of Wenger's recent criticism of Juan Mata's sale to Manchester United).
A target from left field seems likely, then. To make a couple of uneducated guesses: Fabio Quagliarella (Juventus) and Papiss Cisse (Newcastle).
