It's been a fairly quiet start to the summer on the transfer front for Arsenal, with their only signing so far coming in the form of Brazilian youngster Gabriel Martinelli.
Unai Emery is expected to be pretty busy in the window but it's believed that he's working under strict financial constraints, with a transfer budget of around £45m rumoured to be at his disposal. Not much, especially when you see Manchester United paying £50m for Aaron Wan-Bissaka, Manchester City signing the £62.5m Rodri from Atletico Madrid and North London rivals Tottenham breaking their transfer record for Tanguy Ndombele.
The Gunners are one of the biggest clubs in Europe but with them now going into their third successive season without Champions League football, it's evidently hitting their finances.
Controversial owner Stan Kroenke isn't putting the money forward that Arsenal fans demand and need in order to keep up with their rivals both domestically and continentally, so Emery is going to have to do a bit of wheeling and dealing this summer if he's to land his targets.
Celtic left-back Kieran Tierney is believed to be near the top of his shopping list and the Gunners have already had a couple of bids knocked back for the Scotland international. The Bhoys are demanding upwards of £20m for the 22 year-old who's one of the most exciting prospects north of the border.
But it's out wide where they really need to strengthen, with Alex Iwobi the clubs only real natural wide man. The lack of strength in this area led to them playing a 3-5-2 at times last term with Hector Bellerin (when fit) and Saed Kolasinac doing the running at wing-back. This ensured that prolific striking duo Alexandre Lacazette and Pierre-Emerick Aubameyang could line up alongside each other.
But they need a plan B and Emery knows that, hence where the interest in Ryan Fraser and Wilfried Zaha has come from. The pair are up there with the quickest, trickiest players in the Premier League and either would give Arsenal a different option in attack - but they won't come cheap.
The Gunners can realistically only sign one of them this summer but which one should they go for?
