San Jose Earthquakes owner Lew Wolff says any players strike will be a massive setback for the club.

Wolff, like all MLS owners, is growing increasingly concerned over the players' union's threats of a strike as agreement over a new CBA remains at an impasse.

The Quakes owner said: "A strike will be a set back to the dedicated efforts of our players, coaches, management and ownership in seeking to maintain a MLS team in the Bay Area. Without labor being a cooperative partner, our plans for a new venue and expansion of our youth program will be set back for a period that certainly does not benefit the current or future players.

"I feel very close to the players and I am at a loss as to how to respond when I am told that the player's union suggests that they are being treated unfairly. The MLS is seeking to build a strong league for all players, fans and owners. The Earthquakes and the majority of MLS teams did not generate a profit in 2009, nor do they expect to generate a profit in 2010. I believe that the profitability goal should be as much of a concern for the players and their union as it is to the owners.

" All North American sports leagues are facing financial issues due to the economy. MLS is still a young league that is not a fully established yet. To lose the benefits that have been gained to date and to risk League stability is, in my opinion, a risk that the players and their unions need to fully consider."
