Chelsea, who have told Frank Lampard he is free to leave, also remain interested in Bayer Leverkusen’s Andre Schurrle and have also held talks over signing Real’s Gonzalo Higuain but, again, that deal is complicated while the terms to acquire Ba are simple: £7m to release him from his contract, for which he receives £2.5m, plus around £2m in fees to his agent and wages of £70,000-a-week for the striker.
