David Alaba and Samuel Umtiti are two main names on Arsenal's list of summer transfer targets.

The club want to bring in up to five signings in the close-season to set up Unai Emery for a title challenge, and the feeling is deals can be done for both, who would represent significant coups.

Although Alaba and Umtiti have been influential starters for the respective clubs - Bayern Munich and Barcelona - over the last few seasons, changed circumstances would mean both are at least willing to look at the possibility of deals.

Bayern are in the process of a huge overhaul of their squad for next season, with an expected outlay of around €300m, but that will necessitate a clear-out of some long-term fixtures.

Alaba would not be close to the top of the list for potential exits, but there is a sense the German club would be open to talks. The Austrian himself recently talked up his boyhood support for Arsenal. They could however face competition from Barcelona.

Getty Ranking every Arsenal player signed since Sven Mislintat's appointment 8. Stephan Lichtsteiner 5/10. Signed on a free transfer from Juventus, although far too slow to be relied upon as a regular first-team option. AFP/Getty Images Ranking every Arsenal player signed since Sven Mislintat's appointment 7. Konstantinos Mavropanos 6/10. The first signing made under Mislintat's tenure as head of recruitment. Was sent-off last season against Leicester, but still only 21 with plenty of potential. Arsenal FC via Getty Images Ranking every Arsenal player signed since Sven Mislintat's appointment 6. Sokratis Papastathopoulos 6/10. A reliable option at the heart of Arsenal's defence, but £17.6m was an awful lot to spent on a 30-year-old. Getty Ranking every Arsenal player signed since Sven Mislintat's appointment 5. Henrikh Mkhitaryan 6/10. Arrived at the Emirates as part of the deal taking Alexis Sanchez to Manchester United. Has impressed sporadically but is yet to look anywhere near his best. Getty Ranking every Arsenal player signed since Sven Mislintat's appointment 4. Bernd Leno 7/10. Forced to wait for his chance, but now Unai Emery's established number one. Has made the occasional mistake but settling in well. Action Images via Reuters Ranking every Arsenal player signed since Sven Mislintat's appointment 3. Matteo Guendouzi 8/10. Pound for pound, arguably Arsenal's best signing of the last two seasons. Already a regular aged just 19 and a snip at £7m. REUTERS Ranking every Arsenal player signed since Sven Mislintat's appointment 2. Lucas Torreira 9/10. Exactly the sort of player Arsenal have been crying out for years now. Not just a first-team regular, but utterly essential to how Emery wants to play. Getty Ranking every Arsenal player signed since Sven Mislintat's appointment 1. Pierre-Emerick Aubameyang 9/10. A fantastic signing, albeit for a hefty sum. Already has 24 goals in just 35 Premier League appearances and has developed a fine strike partnership with Alexandre Lacazette. Getty Images
