"We are one down in the creative department now that Ali is gone and that is a concern for me," Keegan told www.mcfc.co.uk.
"I won't go into the season with just one creative player," he said. "I may only play with one but I will go and replace Ali if I can.
"I can only do it if I can find the right quality and that is what I am looking for. Everyone is looking for them.
"Eyal's fitness is in doubt at the moment, he is not fully fit yet. If something else happens to Eyal we don't have any cover for that creative role which you need at home more than away."
