Chelsea are considering a summer swoop for Newcastle stars Cheick Tiote and Tim Krul, according to Goal.com.

Despite the sacking of manger Andre Villas-Boas, who was accused of trying to renovate an aging Chelsea squad too fast, changes will still be made in the summer to bring fresh blood into the side.

Both Tiote and Krul have excelled for Newcastle this season as the Magpies have shocked many by still looking good for a top-six finish in the Barclays Premier League.

Ivorian Tiote has been linked with a host of England's top clubs since arriving in the North East from Dutch club FC Twente in the summer of 2010 for £3.5 million.

Liverpool and Macnhester United could also be looking at a combative midfielder this summer and so Chelsea could face stiff competition for the 25-year-old.

Certainly, it is hard to envisage Newcastle selling Tiote for less than £20 million.

Tiote could be an excellent signing for the Blues, though. Ever since Claude Makelele left Chelsea, they have struggled to find someone to consistently fill the holding midfield role.

Mikel John Obi has never fully convinced, while Michael Essien has been ravaged with a series of injuries and his talents are better utilized higher up the pitch.

The rumor surrounding Chelsea's interest in Tim Krul seems a little mor far-fetched, however.

Chelsea still have Petr Cech and while the Czech may not be as formidible between the posts as he once was, it would be a surprise if the club were to wash their hands with him at this stage.

The deal for Krul is made even more unlikely by the fact that Chelsea spent big on young Belgian goalkeeper Thibault Courtois just last summer.

The 19-year-old is currently on-loan at Atletico Madrid, where he has been a regular this season.

There have also been more rumors, today, surropunding Chelsea's search for a permanent replacement for Villas-Boas.

Borussia Dortmund coach Jurgen Klopp has said that, while he is flattered to be linked to the post, he has no intention of leaving his position in charge of the young Bundesliga leaders.

I will not be moving there, he said, according to ESPN. But I do think it is cool that I am being named in the same breath as Mourinho and Guardiola.

That is enough for me - that is already a personal triumph, but I am not available, sorry.''
