4. A cheap deal
Sane's contract expires in June and Arsenal targeting him in January means they could pick him up for a cheap fee. The winger is currently valued at €60m but the Gunners could sign him for significantly less.
The possibility of Bayern offering Sane a new deal is high but if he does not sign, they will be forced to sell him for cheap before losing him for nothing in June.
The Gunners have a good chance of signing a great player for cheap and must exploit the fact Sane's contract is expiring. The club's hierarchy must be aware they can not offer too far below the winger's valuation however as it would mean Bayern could walk away from negotiations. Nevertheless, Leroy Sane would be a great option for Arsenal as he will be much cheaper compared to other wingers on the market.
