Midfielder Luke McCowan says working with “the best players in the country” has already raised his game as he settles in at Celtic. The 26-year-old joined the Scottish champions from Dundee last month and insists he has been a “sponge” soaking up new information. “As you can imagine anybody coming into a club this size, you think it’s going to have daunts and scares or whatever, but it’s not been,” McCowan told Celtic TV.
