Guus Hiddink has warned his successor will face a difficult job of leading Chelsea back to Europe’s elite level and claims the club have fallen behind its competitors, according to Goal.

The Dutchman took over interim responsibilities at the club in December following the departure of Jose Mourinho and although results have picked up since then, the Blues still sit just 12th in the table.

To make matters worse for the West Londoners, they face the prospect of an imminent exit from Europe at the hands of PSG who travel to Stamford Bridge with a 2-1 lead following Tuesday’s Champions League, last 16 first leg, and Hiddink warned that reversing this trend would be no small feat.

It’s not a small job, I don’t want to open up too much but everyone has to make good analysis about the strength of the squad, about the weakness of the squad, and accordingly they have to react in building up, or making the squad stronger for next season. That’s not a small job.

He then went on to talk about the quality of Europe’s top clubs, and claimed that he does not have the same pool of resources to call upon when facing such sides.

If you look at the potential of clubs like Barcelona and Bayern Munich, it is huge. To be honest, if you see PSG, they have a very strong, not just first 11, but can go on to 15, 16, 17 big players. We had some youngsters on the bench against PSG. I am not scared to bring them in but in the long run of a lot of games, you need a bench which is also very experienced.

Italy manager Antonio Conte is now favourite to take over the reigns at Stamford Bridge after the two parties reportedly held talks this week about the role, while Atletico manager Diego Simeone also remains in the frame.

Both managers have experienced great success in their domestic managerial careers; Conte winning three back-to-back Serie A titles with Juventus, whilst Simeone has won La Liga, the Copa del Rey and the Europa League during his stint in Madrid.
