Chelsea continue to show interest in Porto goalkeeper Diogo Costa as a potential long-term acquisition. Sources familiar with the situation have conveyed to CaughtOffside that Chelsea's interest in Costa has been longstanding, sparked by their admiration for his performances at Porto. The Blues are reportedly monitoring the goalkeeper market closely following inconsistent displays from Robert Sanchez. According to CaughtOffside, Porto are reluctant to part with Costa and may require offers around €70 million to consider allowing the 25-year-old to depart from the club.

Last season, Diogo Costa did not show enthusiasm for a potential move to Chelsea.
