Massimiliano Allegri, Juventus' manager, has informed Arsenal that they have until the end of the month to notify him if Arsene Wenger is leaving in the summer and if he is set to replace him, according to the ​Daily Star. 

With Arsenal fans frustrated at their lack of progression, Wenger has come under increasing pressure which has left many to believe his time is running out as potential replacements start to be discussed.

Juve's desire to tie Allegri down with a new contract - his current deal expires at the end of next season - reflects his success with the Italian giants as they sit eight points ahead of Roma as the 49-year-old closes in on a third successive league title.

However, with Wenger refusing to reveal whether he is staying or not is complicating the issue of identifying who will need to replace him if he calls time on his 21-year managerial career at the Emirates.

Allegri's credentials have alerted a number of top European clubs, including Barcelona - who's boss Luis Enrique is standing down this summer- and Paris Saint-Germain could also be looking to replace Unai Emery after their 6-1 thrashing at the hands of Barca on Wednesday. 

The uncertainty surrounding Wenger is causing issues for Arsenal's owners negotiating with Allegri as he has made it clear he is not prepared to be left waiting as other inviting offers come his way. 

Arsenal fans continue to protest against Wenger, with plans to continue to show their frustrations on Saturday for their FA Cup tie against Lincoln after recording only two wins in seven, in all competitions, which has left many supporters to call for change. 

With rumours growing louder throughout the season suggesting Allegri will depart Juventus this summer, Arsenal will need a definitive answer from Wenger soon if they are to stand a chance of landing the Italian.
