After watching from afar as Chelsea splashed the cash on disappointing arrivals year after year, Xabi Alonso has arrived to take charge from the technical area and play a key role in the transfer market.
The Spaniard has already welcomed Marco Palestra and now has his sights set on signing a key upgrade on Robert Sanchez ahead of next season.
The Blue, with Alonso at the helm, could finally land long-term target Diogo Costa as a result.

Costa is once again one to watch this summer, as he potentially swaps Porto for a big-money move that's been years in waiting.
Chelsea readying offer to sign Diogo Costa
According to Correio da Manhã in Portugal, as relayed by Sport Witness, Chelsea are now readying an offer to sign Costa from Porto this summer, with Alonso driving the move.

The Blues reportedly value the goalkeeper at €40m (£34m), but Porto are already pointing towards the goalkeeper's €60m (£51m) release clause - creating an instant gap in valuation.
With Bayern Munich and Paris Saint-Germain also interested, the West London club are looking to leap ahead of their European rivals and may have to spend big if they want to land a rapid-fire deal.
£51m Costa would end Sanchez's Chelsea career
Chelsea have rarely got things right in the transfer market under BlueCo, but Costa would be a rare standout. The Porto man is one of the most reliable goalkeepers in Europe and would be an instant upgrade on Sanchez, perhaps even ending the Spaniard's Stamford Bridge career.

Save percentage 67.6% 80%

Costa conceded just 15 league goals at Porto last season and kept a save percentage of 80%. He is one of the best goalkeepers in Europe and should be top of Chelsea's wishlist this summer.
