Chelsea have reportedly added Jon Martin Vicente to their shortlist of transfer targets. The Real Sociedad defender is rumoured to be attracting attention ahead of the next transfer window, with insiders claiming preliminary talks could soon take place. Chelsea have laid out their intentions, but valuation and timing remain under debate. Arsenal are keeping tabs in case talks collapse or progress slows further. So far in this season, Chelsea are conceding 2.4 goals a game (12 in 5), more than they'd like compared to the Premier League standard. The hope is Jon Martin Vicente adds a bit of steel and helps make them tougher to break down. Speculation continues to connect Chelsea with Francesco Camarda, Conrad Harder and Nicholas Williams while no fresh rumours surround Real Sociedad.
