Celtic could soon face another decision over Arne Engels as West Ham continue their push to sign the Belgian midfielder. That sale gives West Ham more room to improve their proposal, although there is no guarantee their next bid will meet Celtic’s valuation. West Ham are also likely to want any deal completed before their own league campaign begins on 16 August. Neither situation is yet at a stage where Celtic could simply replace Engels without further talks. For now, Engels remains available to O’Neill and continues to play despite the transfer interest.
