Ander Herrera's impact at Manchester United under Ole Gunnar Solskjær should not be underestimated.
The United midfielder is out of contract at the end of the season and has been heavily linked with a move to Paris Saint-Germain.
Since the United boss' arrival at Old Trafford back in December, Herrera was one of the players to dramatically improve under the 46-year-old Norwegian and, as a result, found himself securing more match time.
According to WhoScored, the Red Devils had a much better winning record when the former Athletic Bilbao star was in the starting XI than when he was left out of it.
In the nine matches that Herrera started, Solskjær's men won eight times and picked up one draw. United scored on average 2.22 times and conceded 0.44 times, with the Spain international showing how important he can really be in the United midfield and helping his side to secure a win.
So, what are the stats like without him?
Well, it's not a pretty sight.
Without Herrera being in the starting XI for eight matches, United have won four times, picked up a draw and suffered three defeats. The Red Devils have scored on average on 1.75 times and have conceded 1.88 times, too.
Earlier this month, Herrera revealed that he and the club were not on the same wavelength.
"It is true that I have only two months of contract and today Manchester United and I are not thinking the same and there is no renewal agreement, but my duty is to continue listening to United," he told Diario ABC.
"I will listen to United, of course, but also to other clubs. I do not close doors."
United continue their pursuit of a top-four finish when they host Manchester City at Old Trafford on Wednesday.
Solskjær will be hoping for his side to bounce back from their 4-0 thrashing at the hands of Everton on Sunday.
Should Herrera stay at United or leave in the summer?
