OB are challenging FC Basel for Liverpool striker Liam Millar.
The Canada international is up for sale at Anfield and has seen an offer from Basel turned down.
Liverpool are encouraging Basel to up their bid, while Denmark's OB are also keen.
The Reds are seeking around £2m to sell Millar.
The 21 year-old striker made his debut for the Reds in the FA Cup match against Shrewsbury in February 2020.
