Would+this+have+to+lead+to+higher+unemployment?

Higher wages do not always lead to unemployment. So for example if a worker is able to increase their productivity by 10% the firm can afford their higher wages. How easy is it to substitute capital for labour? EPL footballers are getting higher wages because their is no real substitute for their labour are the firms monopolies earning very high profits. If so they'll be able to absorb these higher wages in the form of lower profits. Also can the firm pass on the wage increases to the customers. Again a non competitive market where there no real substitutes means that firms can pass on these wage increases to the customers, so unemployment need not occur.
