He is getting on for 27, say 4 years left at the very top and not much of a sell on fee if we let him go then.
Spurs bought him for £10.6
Bayer Leverkusen 152 games 68 goals
Spurs 52 games 20 goals (including the 4 against Reading) And only 4 premiership goals last season.
His attitude is questionable as is his consistency and his teamwork, he has wonderful gifts and can do things on a football pitch many others would not dream about but this does not amount to a 25 million pound player.
I’d consider taking him for £15 million or less but not a penny more!!!
