He will be reunited with Angelo if he does become a Chelsea player. He was also set to move to Strasbourg, the club Chelsea chiefs recently acquired.
However, GianlucaDiMarzio.com claims that there is now a chance he could stay at Stamford Bridge this season. Pochettino has been impressed by the wide attacker and views him as part of his plans.
Angelo came off the bench in the friendlies against Fulham, Brighton and Wrexham. He was an unused substitute for the 1-1 draws against Borussia Dortmund and Newcastle.
Meanwhile, Chelsea are set to sign Brighton goalkeeper Robert Sanchez. A fee of £25m was agreed between the two Premier League clubs on Friday and he is expected to provide competition for fellow Spaniard Kepa Arrizabalaga.
