Tammy Abraham has welcomed Chelsea's move for Timo Werner, according to reports.
The Blues have reportedly agreed to meet Werner's £53m release clause.
The move has called Abraham's future into question, with Lampard favouring a 4-2-3-1 formation this season.
But Abraham is relishing the challenge of fighting for his place in Lampard's team, according to The Athletic.
The England international was under no illusions about Chelsea's desire to bolster their attacking depth this summer.Abraham remains confident after a stellar campaign for the Blues, in which he has scored 13 goals in 25 league appearances.
