Speaking to Betfair, Berbatov said: "I still think the first-choice manager for Liverpool is Xabi Alonso, especially if he wins the Bundesliga with Bayer Leverkusen. That would be a great success. If that happens, Alonso will likely take the next step to Liverpool. Some may say it's a bit too early, and maybe he'll have one more season with Leverkusen and he'll try to go for European glory with them to prove to everyone the Bundesliga win wasn't a fluke. However, I think Liverpool should continue to chase Alonso.
"If they can't get him then there are other coaches on the market like Thomas Tuchel. Tuchel would be the next contender for me to replace Klopp if they miss out on Alonso. Sometimes clubs will try to play it safe based on the manager's reputation or sometimes clubs take a chance and go for a not-so-big name, but at Liverpool, they have to go for success, and I think Tuchel or Alonso would be a good fit."
