Wenger admits Arsenal will always struggle to compete with the likes of Paris St Germain, the French club bank-rolled by the same Qatari royal family who have made their mark on London.
The Arsenal boss said: “PSG have unlimited resources. If they decide to go to £100million, they do it.
“If they decide to go to £150m, they do it. They have a building called The Shard that cost £1bn, that was built by Qatar. They have unlimited resources. I cannot promise we will match them.
“Is it more about keeping players we have? Yes, of course.”
