These two behemoths of the English game have both shown a more than key interest in United's former star player.
Having been torn apart by Wayne over the past decade or so, both managers and players at the two English clubs primarily involved in the Rooney saga know exactly how valuable he is.

Mirror has reported that Arsenal have made a bid in the region of £20 million for the United striker, which has so far been met with silence from Old Trafford.
Whilst this sum isn't going to be enough to lure Rooney to the Emirates, it does lay down the real intentions of Arsene Wenger this summer, and it gives Wayne some food for thought.
Clearly the man who is now the longest-serving manager in the Barclays Premier League has his eye very firmly set on the England International.
The move would make sense for both player and club, with Rooney ironically filling the void left behind with the departure of Robin van Persie.
Is this likely to happen? I think not, simply because of the rivals Arsenal have for "Wazza." Whilst Wenger has been handed a huge cash kitty this summer, competing with the likes of Chelsea, PSG and Real Madrid will surely be too much for the side that have gone eight years without a trophy.
According to James Boylan's report in Metro Chelsea are poised and primed to up the ante and outbid Arsenal some time this week if it does become apparent Rooney will not be staying at Old Trafford.
In truth Chelsea are the kind of club where if they want a player, they almost certainly have enough money to be able to lure them in.
That, along with the recent arrival of Jose Mourinho and all-round upheaval at the club, plays perfectly into Rooney's hands from an on-field perspective.
Jose appears to be on the hunt for a striker this summer, with rumors of Fernando Torres heading to Arsenal showing an obvious intent to find a new center forward, according to the Sunday People (h/t Yahoo! Sport).
Whilst Edinson Cavani is being touted as the likely newcomer to the role, that doesn't stop Mourinho strengthening further and acquiring Rooney also.
Don't be surprised to see Jose placing a bid for the United man some time this week in excess of £25 million.
