Website Football Insider is reporting that the Blues are looking to get one over their London rivals by hijacking their bid to sign Allen.
The same article states Allen went on a trial at Tottenham before holding talks about a potential move to the Champions League runners-up.
According to the same story, Chelsea FC have also contacted Allen’s club Linfield to organise a trail at their Cobham training ground.
The report goes on to add that the Blues hope to beat Spurs to Allen’s signature.
However, Football Insider reveal that Manchester City are also keeping tabs on the 15-year-old starlet.
Chelsea FC have developed a reputation for giving youth a chance since Frank Lampard took over the reins of the west London club.
The Blues boss has given Tammy Abraham, Fikayo Tomori and Mason Mount the chance to shine in the Chelsea FC team.
Abraham is the Premier League’s leading goal-scorer after netting eight goals in eight games.
Chelsea FC are in fifth place in the Premier League table after winning three of their last four games.
The Blues will take on Newcastle United at Stamford Bridge next Saturday.
