Former Hull City boss Ian Holloway says Tammy Abraham is good enough to lead the line at Chelsea.
The striker has broke goalscoring records on-loan with Aston Villa this season.
Holloway told the Daily Express: "Thank God they've got a transfer ban; who else are they going to buy who's over 30? Seriously, that ain't the way to run a football club. If you buy someone who's over 30 then you're never going to get your money back.
"I believe, now, he's proven at Championship level, he'll go back [to Chelsea] and he will score goals in that top side.
“Particularly a side like Chelsea because they will dominate the ball and create a lot of chances. Put him in the Man City team up front with a number 9 on his back - would he score? Course he would.
“It's about time Chelsea got rid of these mercenaries coming over there, trying to keep their manager in a job. Build a club, build a team.
“And if you're not going to do that, stop stacking and racking the best young players around. Let other people have them and let them play."
