The Toffees’ main priority ahead of the coming transfer window is believed to be keeping hold of the on-loan Chelsea star, but rumours suggest that they may struggle to do so.
Lukaku himself is eyeing Champions League football and is valued at over £20m, which may both work against Everton.

However Welbeck is likely to be valued at around £20m, which may be a stumbling block for the Spaniard.
