Bristol City boss Lee Johnson believes Chelsea striker Tammy Abraham's value is on the rise.

Abraham has enjoyed a prolific stint on loan at the Championship side, scoring 25 goals in 45 appearances.

And Johnson said: "He's been a fantastic signing for us. We appreciate it from Chelsea, but we've done well for Tammy and Chelsea.

"The market value has shot up on him, if they ever want to sell him, but also we've helped develop him.

"That only comes from Tammy being such a good lad and working as hard as he has. This will be an unbelievable learning curve for him."
