Manchester United may have noted Arturo Vidal's excellent performance against Chievo with envy, but the Chilean's frequent injury problems will ease any jealousy.
Vidal was repeatedly linked with Manchester United during the summer but the transfer window closed with no news, despite press reports of mammoth bids.
It was suggested that United boss Louis van Gaal wasn't convinced by Vidal's fitness after recent knee problems and the gifted midfielder has continued to be plagued by injury.
After shrugging off his knee injury to start the Serie A opener and impress in a 1-0 win over Chievo, Vidal was again limping while on international duty.
Vidal will undergo tests later today to ascertain the extent of the problem and will have to take it easy for a little while before rejoining his teammates.
While nobody is suggesting a lengthy lay-off, Vidal has been accused of being injury-prone and his latest setback may have justified Manchester United's reservations.
Nobody can questions Vidal's efforts on the field but when a side pays £40 million for a player, they cannot afford for him to spend significant periods of time on the treatment table.
It remains to be seen whether United are willing to take a risk on Roma midfielder Kevin Strootman, who has been sidelined since March with a cruciate ligament knee injury.
Strootman is close to full fitness again now, but knee problems are notorious for recurring and, like Vidal, the Dutchman will carry the stigma of being seen as fragile.
