Receiving £77m just one year after paying roughly £60m would represent a healthy return, while Arteta already has extraordinary depth following the Guimarães signing.But selling Zubimendi directly to Chelsea carries obvious danger.Alonso already understands the midfielder’s qualities, and Zubimendi could immediately become a key player in a Chelsea side expected to challenge Arsenal near the top of the Premier League.Strengthening a direct rival should therefore come with a significant premium.Arsenal also need depth. Guimarães can play both as a defensive midfielder and further forward, and sporting director Andrea Berta specifically highlighted his versatility when the deal was completed.That flexibility means Zubimendi does not necessarily have to leave.If Chelsea meet the full £77m valuation and Zubimendi pushes for greater guarantees over playing time, Arsenal would have a difficult decision.Sky Sports man confirms European heavyweights have submitted an official bid for Arsenal starThe post Arsenal ready to consider big money sale as Chelsea remain interested in midfielder appeared first on CaughtOffside.
