Frank is working to bring in reinforcements for multiple positions, and his top transfer target is West Ham's Mohammed Kudus. The club has already submitted multiple bids which have been rejected, but Frank is still keen on signing the Ghana international.

Should a move materialise, the 24-year-old would follow Mathys Tel to Tottenham, after his loan move from Bayern Munich was made into a permanent switch for a sum of £30m. Soon, Rodrigo Muniz could also become a Tottenham player, after Fulham identified a replacement in Tolu Arokodare.

West Ham have rejected a £50 million ($69m) bid from Tottenham for midfielder Mohammed Kudus, a source has told ESPN.
