Arsenal chairman Sir Chips Keswick can't guarantee keeping hold of contract rebels Mesut Ozil and Alexis Sanchez.
Keswick, though, has warned that with extra revenue comes bigger demands from clubs and players alike, with Ozil and Sanchez still locked in negotiations.
The key duo entering the final 16 months of their current contracts as speculation continues over their futures ahead of the summer and the club chairman has sounded a "note of caution" regarding ever-increasing expenditure.
"As expected, increased Premier League broadcasting revenues had had a direct impact on player costs both in terms of transfer prices and player wage demands," he said.
"Whilst these are the market forces that have contributed directly over time to the success of the Premier League, I would sound a note of caution in light of the very material contractual commitments to future wages that clubs are taking on."
