Chelsea are preparing to land Kun Aguero.

After their January transfer ban was lifted temporarily, Chelsea are willing to blow their entire transfer budget on the young argentine.

The son-in-law of Diego Maradona has a £50million buy-out clause in his contract with Atletico Madrid, who might be persuaded to accept only £35m. But Maradona is urging him to join Inter Milan at the end of the season, which would not disrupt his World Cup preparations.

Another problem is the incoming 50 per cent tax rate in the UK, although that will be affected by the change in Spanish tax laws that come into effect on January 1st.

Chelsea would have to pay him £170,000 a week to match his earnings in Atletico, which is in excess of their top earner John Terry.
