Chelsea Transfers: 10 Players Antonio Conte Should Sign This Summer

10. Romelu Lukaku

They say you should never go back to an old flame. However, Chelsea have proved that time apart can actually reignite a relationship.

After sending Nemanja Matic packing to Benfica as part of the original David Luiz deal in 2011, they decided to bring the Serbian powerhouse back to the Bridge in 2015. The time away seemed to work wonders for the midfielder as he has played a pivotal role since his return.

Brazilian defender Luiz is another player the Blues have seemingly made the right call in re-signing. Often looked upon as a bit of a calamity in his first spell with the club, his successful sabbatical at Paris Saint-Germain made the Londoners offer the big-haired blocker another chance.

So, what about another former player returning to his old stomping ground? Belgium's Romelu Lukaku was highly rated by the coaching staff and fans in West London, but a desire for first-team football saw the now 24-year-old depart for Everton after a successful loan spell at Goodison Park.

After establishing himself as one of the Premier League's most prolific goalscorers in recent seasons, it's no surprise that he's been strongly linked with the champions.

With his time on Merseyside almost certainly up after the player rejected a new contract and stated a desire for Champions League football, many see him as the perfect replacement for the outgoing Diego Costa.
