Manchester United and Arsenal have joined QPR and Stoke in the pursuit of Celtic midfielder Victor Wanyama.
Scouts from each club watched the Kenyan, 21, in Celtic’s 1-0 defeat by Norwich on Tuesday.
He has voiced his frustration at being played in defence and rather than defensive midfield. He is keen to move to England.
Celtic want around £7m but are concerned they could lose Beram Kayal also.
The Israeli midfielder, 25, is attracting interest from Southampton.
