Fifth to finish could be Vincent Kipchumba, also known last year as Vincent Toroitich, 29yo and ranked 6. Won Vienna in 2.06.56 and Amsterdam in 2.05.09. Previous best was 2.10.32 when second in Dresden in 2016. Experts at year end 2019 selected him top ten on the basis of those two wins. I lined them up against Shifera Tamru who had two times under 2.05.30 and placed Vincent outside my top twenty.
With Lemma now added, I would place him fifth: just before Vincent. I thought after the last great marathon in Tokyo, Sisay was the ninth best among his peers.
