Riyad Mahrez and Jonny Evans look set for moves to Liverpool and Arsenal this month, according to Ladbrokes.
The bookies can report the pair's odds of a January transfer have been notably slashed, with Mahrez now odds-on at 2/5 to swap Leicester for Liverpool.
Evans was as big as 20/1 last week for an Arsenal move, but his odds have been slashed to just 6/4 following the Gunners' embarrassing defeat to Nottingham Forest.
Elsewhere, Jonjo Shelvey is now 1/2 (from 11/10) to join West Ham this month, while Thomas Lemar is an even-money shot to sign for Liverpool.
Alfie Mawson looks likely to leave Swansea during this window and his odds of joining Watford have been substantially cut from 12/1 to just 13/8.
Alex Apati of Ladbrokes said: "It's been a huge weekend as far as transfer betting goes, with several players now looking more likely than ever for big money moves.
