The loan market is a vital tool for Premier League clubs (outside the top six) and lower league clubs.

Whether that be to bring in immediate injury replacements or quality that your club is financially unable to outlay, the loan system is the backbone for successful squads nowadays.

Chelsea are one of those clubs who choose not to sign players on loan.

So, in light of Mateo Kovačić arrival, we look back at the four loan signings Chelsea have made in the Abramovich era.

Maniche signed in January 2006, midway through the campaign that would see Chelsea retain the Premier League title.

He failed to play enough games to earn himself a winners medal, competing with Michael Essien, Frank Lampard and Claude Makélélé for a place.

Chelsea could have made his move permanent at the end of the season for just £5m – but decided against it.

Another Portuguese player who failed to make an impact at Chelsea when signed on loan.

Quaresma signed in February 2009 after winning the ‘Bidone d’oro’ award – given to the worst player in Italy.

Despite failing to have a meaningful impact – he only made five appearances – Quaresma left saying that his confidence was restored.

This is one transfer that I wish worked out well but, alas.

Pato signed in the January 2016 and made his debut in April, where he won a penalty and converted it.

This was not enough to convince the Chelsea hierarchy however as, after making just two appearances, he returned to Corinthians.

Falcao – Monaco

The most recent in the line of loan failures.

Having failed to make an impact at Manchester United, Falcao was brought in to provide competition with Diego Costa.

However, his injuries had taken a toll on him and he eventually returned to Monaco.
