Dynamo Kiev defender Domagoj Vida has reportedly emerged as a transfer target for both Everton and AC Milan.
At the start of the season, both the Toffees and Rossoneri had high hopes of an improved campaign, with the main target securing Champions League football for the next season.
However, Everton are currently sitting just above the relegation zone in the Premier League table, while Milan are seventh and 13 points off the pace in Serie A, and it appears to have led to the two clubs looking to strengthen in defence in January.
According to Ukrainian outlet Futbol, Croatian international Vida is a wanted man with his contract expiring at the end of 2017.
The 28-year-old has been a regular in Kiev's Europa League campaign this season, while the left-back is also a regular with his country having started both of Croatia's World Cup playoff games with Greece.
