I want to know the answer to the following question:
Who was the Everton FC team's longest serving manager?
All the background I'm provided with is that "The Everton manager to win most domestic and international trophies is Howard Kendall, who won two Division One championships, the 1984 FA Cup, the 1984 UEFA Cup Winners' Cup, and three Charity Shields.". Is that enough to answer the question?
Answer: no
