Chelsea striker Tammy Abraham is being linked with Derby County.
Abraham spent last season on-loan with Swansea City.
Former West Ham striker Dean Ashston told The Sun: "They [Derby] ran out of steam towards the end of last season, stumbling into the play-offs and paid a hefty price.
"They lacked spark, energy, that extra five per cent which could have made all the difference as they lost in their play-off clash with Fulham.
"How about Tammy Abraham? Yes, he has admirers in the Premier League after spending last season on loan at Swansea form Chelsea, but he could be tempted to work under Lampard.
"And he'd be back in a league where he bagged 23 goals in 41 appearances for Bristol City a couple of years ago."
