Germany's Shkodran Mustafi and Italy's Simone Zaza in action
Arsenal's top transfer target is German defender Shkodran Mustafi, but they appear no closer to getting a deal over the line.
Their weak injury hit back line was exposed by Liverpool at the weekend as they conceded four goals and slipped to a defeat.
The Mirror report their attempts to sign Mustafi from Valencia are being complicated by Everton, a team the German once played for as a youngster.

Everton have recently signed Ashley Williams from Swansea but are keen to add another defender, and Sunderland's unwillingness to sell Lamine Kone has them looking at Abdennour.
For Arsenal it is just a headache they could do without, with time running out, and their need to add a defender even more important than Everton's, due to their injury crisis.
Mustafi was linked early last week as soon as Gabriel Paulista went down, and time is ticking away towards the end of the transfer window.
The closer it gets to deadline the harder it will be to convince Valencia to sell, as their own time to sign a replacement will be shortened.
