Tottenham Hotspur are tracking the progress of Anderlecht full back Jordan Lukaku, younger brother of on-loan Everton star Romelu, reports suggest.

The 19-year-old has impressively progressed through the Belgian's club's youth ranks before joining Jupiler Pro League side KV Oostende on a season long loan this campaign, where he has made six starting appearances so far.

Lukaku, who predominately operates as a left back but has also been utilised as a winger, has also caught the eye of Serie A giants AC Milan, who were impressed with the teenager's performances during a youth tournament earlier this year.

But Tutto Mercato Web suggest the Rossoneri will face competition from Spurs, who are planning to launch an opening bid for the Belgium Under-21 international with the view of him moving to White Hart Lane next summer.

While Andre Villas-Boas has assembled a fine squad as Tottenham aim to once again crack the top four and qualify for the Champions League, the left back area of his side is one area he remains light in.

The Portuguese manager has adequate cover for every position in his first XI except for on the left hand side of his defence. After his impressive spell on loan to Sunderland last season, Danny Rose has returned to White Hart Lane to fill the role, but following the departure of Benoit Assou-Ekotto who has joined Queens Park Rangers on loan, he has no direct competition for his spot.

Kyle Naughton and Jan Vertonghen were both utilised as a makeshift left backs last season but Villas-Boas is understood to be interested in signing another natural full back to provide competition for Rose.

Romelu Lukaku, who is enjoying a second successive spell away from Chelsea at Goodison Park this season, has previously touched upon the idea of his younger brother Jordan joining him in the Premier League, claiming his sibling is the more technically gifted player of the two.

"I have loved Chelsea since I was a boy. Now that I have fulfilled a dream by joining Chelsea, my final one is to have my brother join my one day," Lukaku said upon completing his move to Stamford Bridge two years ago.

"It's our dream to lay in the same team. We have done it in friendly games but, one day, we hope to do it when it matters.

"Technically he is better than me. He is a left winger who is very skilful and strong. I think when the scouts see him, they will see what he can do."
