Villa are looking to bolster their midfield region and have earmarked Phillips as an ideal candidate to marshall that area.
The 23-year-old has progressed immensely under Marcelo Bielsa last season. He made 44 Championship appearances and was outstanding in the middle of the park.
He developed into such a key player that Leeds are determined to hold on to him at any cost. However, each player has a price, and Leeds are demanding £30m for the midfielder.
According to reports from The Sun on Sunday (printed edition, page 59), Villa are preparing a tempting bid in the region of £20m for the highly rated midfielder.
Leeds have already rejected a previous bid from Villa for Phillips, and they are adamant about keeping him this summer.
He is a key part of Bielsa’s system, and is central to Leeds’ hopes of securing promotion to the Premier League next season.
