Former Super Eagles and Chelsea star John Obi Mikel has undergone a successful surgery in the United Kingdom.

The Nigerian football icon disclosed this in a post on his Instagram story on Saturday while sharing photos of him before and after the operation.

The 37-year-old, however, did not disclose the nature of the surgery.

He shared two pictures, one taken before the operation with the caption “Pre-op, let’s go,” and another post-surgery while lying on the hospital bed, captioned “All good, #PostOp.”
