"Newcastle are also trying to land Chelsea winger Kenedy for around £20m and the player is keen to sign for the club permanently after spending the second-half of last season on loan on Tyneside.
"However, a potential stumbling block in those negotiations is that Chelsea will insist on a buy back clause in his contract."
When signing a player who would almost certainly break your club record fee, I can see the reluctance to include a clause that would see him leave, but I wouldn't have too many problems including a hefty buy back clause for Chelsea.
If we can sign him for 'around £20m', I'm pretty sure we'd all be delighted - regardless of any clauses put in place.
