Liverpool have sent scouts to Portugal to run the rule over Benfica's emerging starlet Lazar Markovic in tonight's Europa League clash, reports the Daily Mail.
The 20-year-old has impressed observers throughout the season and is due to start against AZ Alkmaar in the quarter-final second leg, which Benfica lead 1-0.
Brendan Rodgers is looking to invest in promising players this season as the Anfield club prepare for a return to the Champions League next season.
Markovic has also attracted the interest for Manchester United manager David Moyes, who has himself dispatched scouts from Old Trafford to watch the flying forward.
Moyes himself is preparing to overhaul the Manchester United team in the summer after a disappointing start to life as Sir Alex Ferguson's successor.
Liverpool will also face Chelsea should they decide to move for Markovic with Jose Mourinho currently considering another raid on Benfica.
Mourinho signed Nemanja Matic from the same club in the January transfer window and was reportedly considering a £12.5m move last month.
Markovic is considered one of the top young players in the whole of Europe and has already been capped by the Serbian senior team 10 times.
Rodgers has also told his scouts to keep an eye of left-back Guilherme Siqueira, who was subject of a failed offer from Liverpool last summer.
Liverpool's struggle to find a reliable left-back this season has forced Rodgers to consider renewing his interest in the 27-year-old this summer.
