Ole Gunnar Solskjaer’s comments about Alexis Sanchez after his performance against Paris Saint-Germain were damning.Since his arrival at the club, the Norwegian has only spoken positively about his players, trying to encourage them after the dark days of Jose Mourinho.But he couldn't help admitting that he is struggling to help Sanchez, who played the entire second half after replacing the injured Jesse Lingard in first-half stoppage time.“I can’t do anything about Alexis Sanchez,” Solskjaer said, per the Telegraph.“When he plays he needs to find himself because there’s a quality player there.”It seemed that, with Lingard and Anthony Martial both suffering injuries against PSG, Sanchez would be handed another opportunity to regain his form in Man United’s FA Cup tie against Chelsea on Monday.But the 30-year-old is himself battling to be fit for the clash after being injured in a freak incident before coming on against the French club.

Sanchez's freak injury v PSG

According to the Daily Mail, Sanchez was hurt after colliding with a linesman during his warm up.

Journalist Simon Peach tweeted about the incident at the time it happened.

But it wasn't clear then that Sanchez actually injured himself.

The forward was readying himself to come on in place of Lingard, who strained his hamstring late in the first half.

But the former Arsenal man became distracted by the action on the pitch as he jogged along the touchline and he ran straight into linesman Fabiano Preti.

Sanchez was floored by the incident but he was still able to come on.

He informed Man United’s coaching staff that he had suffered an injury above the knee and the decision was made to keep him on to prevent his leg from stiffening up.

Sanchez warmed up in a training top at half-time, too.

It’s another embarrassing setback for Sanchez, who hasn’t enjoyed an easy ride since joining the Red Devils on a £500,000-per-week deal 13 months ago.

The Chile international was injured when Solskjaer came in and he’s started just three games out of 12 under the caretaker boss.

His performance in the second half prompted those comments from Solskjaer, who will be far from impressed if he’s unavailable for the Chelsea clash.
