The Portuguese boss has been pleased with his squad at the start of the season, especially following the 4-0 victory over West Ham, however, has realised he needs more pace between the lines and on the flanks.
Mourinho was looking to sign Perisic at the start of the summer as Inter were hoping to comply with Financial Fair Play regulations but after raising the funds through smaller deals, they’ve been set on keeping hold of their star asset.
Inter have been in talks with Perisic’s agent as they hope to give him a bumper new contract even though Chelsea are also monitoring developments.
The 28-year-old was identified as the player with the ability to cut inside and interchange with his forwards, but he seems set on staying at the San Siro.
Mourinho has allegedly been concerned that his side does not always move possession quickly enough with some of his midfield attacking options getting pushed off the ball.
Perisic would have been the player to solve his problems and although a deal has stalled, there is still time to get a deal over the line.
