Bill Casey and Nick Kissack, former senior European equity analysts at Janus Henderson will join Schroders in February next year as fund managers.
The duo, who have worked closely with John Bennett (pictured) director of European equities, since 2011 and 2014 respectively, went on gardening leave last week but will officially leave Janus Henderson in January.
They will join Schroders' pan-European equities team as fund managers, though it is not yet known what their responsibilities will be.
Rory Bateman, head of European equities at Schroders, said: "We are delighted Bill and Nick are joining Schroders in early 2018. They are extremely high calibre investors with excellent experience in UK and European equities."
Meanwhile, Asim Rahman, who worked alongside Bennett as co-manager on the £2.3bn Henderson European Selected Opportunities, £550 Henderson European Focus and €4.4bn Henderson Gartmore Continental European funds will also leave the firm in January.
As a result, ratings agency Morningstar have put the three funds under review.
While four analysts and co-managers remain on the European equities team, Casey and Kissack have "good levels of experience and were more focused on individual strategies", according to Morningstar.
The three funds had a rating of 'silver' but have now been put under review, awaiting any potential changes once the agency has spoken to Bennett.
Morningstar added: "We understand the group is looking to replace the lost resources immediately.
"We consider these changes to be material and are therefore placing [the funds] under review until we speak to Bennett in the coming week."
A spokesperson at Janus Henderson said: "Bill Casey and Nick Kissack, who provided fund manager support to the broader equity team, have left to pursue further opportunities outside of the firm.
"Asim Rahman, who has worked here for eight years is leaving to spend more time with his growing family and to explore new opportunities too. He is going to stay at the firm until the end of January 2018 to ensure a smooth handover to the rest of the team.
"There will be limited impact on our European equities franchise as a result of these changes."
