We are led to believe that Chelsea will be making a couple signings before the summer transfer window is over, as unlikely as that may seem amid the deluge of rejected bids and failed pursuits. Sure, we signed a third-choice goalkeeper; meanwhile, AC Milan went as far as releasing an official statement to deny any potential Alessio Romagnoli transfer. Clearly, they're all just trolling us now.
Since center backs (not named Mustafi, apparently in whom we were not really interested) seem to be ungettable, maybe the thing to do is to go after a couple full backs. Ricardo Rodriguez and Stephan Lichtsteiner have been mentioned, but Mr. Oracle has a new name for us to ponder.
Marcos Alonso, once of Real Madrid's academy, is a 25-year-old full back whom we may actually remember from his days at Championship side Bolton Wanderers. He won their player of the year award back in 2012-13 before joining Fiorentina that summer. He did return for a brief half-season loan to Sunderland once, helping Gus Poyet to a miracle relegation-escape. Alonso has been La Viola's first-choice left back ever since, and has apparently done fairly well.
The name may not be the most inspiring, but there's a hint of an Azpilicueta about this. Alonso's tall, reasonably quick, and can run all day (when he's not injured). Able to play left midfield or even as part of a back-three, the Spaniard is possibly available for under £20m.
