Marc Cucurella was left out of Brighton's squad to face Espanyol on Saturday after putting in a transfer request.
The 24-year-old has been given time off after Brighton rejected Manchester City's latest bid for him and refused to engage in further negotiations unless City meet their £50million plus valuation. Cucurella and City believe the valuation is unrealistic.
City have offered around £35m and were willing to push to £40m but that is not good enough for Brighton who value left-back Cucurella highly.
Cucurella's Premier League experience makes him an appealing option for City, but Brighton's valuation of him is proving to be a stumbling block.
