Both aforementioned Premier League heavyweights have been linked with the Argentine centre-back in recent weeks, with Fazio having proved instrumental during the La Liga outfit's encouraging 2013/14 campaign.
As reported by talkSPORT, Napoli are also believed to hold a keen interest in the 27-year-old, yet Ariel Kiperszmid has been very keen to stress that his client is attracting glances from all over the continent - including England.
"Napoli? They are not the only club on his trail, he is an established player at European level and coveted by many teams.
"Fazio is wanted in Italy, England, Germany and beyond."
And while Kiperszmid was quick to highlight the attention Fazio is receiving from clubs outside of Spain, he also did not rule out the possibility that the two-cap Argentina international - who will not travel to the World Cup this summer having been left out of Alejandro Sabella's squad for the tournament - could have his current £8 million buyout clause increased by Sevilla.
"Now he thinks about Sevilla as he is fresh from winning the Europa League and is enjoying the moment," he added.
"He has a contract until June 2018 and a buyout clause, and it is not inconceivable that Sevilla will increase it."
A tall and solid defensive presence, Manchester United could certainly use a player of such stature this summer with the experienced duo of Rio Ferdinand and Nemanja Vidic set to leave Old Trafford at the end of their contracts.
Arsenal are presumably not quite as desperate to reinforce their own defence with Per Mertesacker and Laurent Koscielny having developed quite an understanding at recent times.
However, with both Bacary Sagna and captain Thomas Vermaelen - two experienced, established and versatile international defenders who can occupy positions both in the centre of defence and at full-back - expected to depart the Emirates Stadium, Arsene Wenger may be keen to ensure that he has adequate options in reserve.
