Jose Mourinho SLAUGHTERS Frank de Boer after Marcus Rashford criticism

Sunday's clash was the first Premier League match Rashford - one of English football's brightest prospects - had started in 2018.

This season, the England worldwide has now scored six times in the league, but he has mostly been used as a substitute.

After Marcus Rashford bagged a brace in United's 2-1 win over Liverpool on Saturday, De Boer took aim at Mourinho.

"He can make mistakes but Mourinho is not like that and if he has one or two not good games then he puts him out".

"Tomorrow is a very hard match, we are playing against a team that didn't lose against Liverpool home and away", said Mourinho.

The former Chelsea manager has not just talked the talked though but has also walked the walked as Marcus Rashford was the only player involved in every match-day squad prior to his injury.

Rashford is in line to start the second leg of the Champions League round-of-16 tie against Sevilla at Old Trafford on Tuesday night after that performance against Liverpool. "He wants to get results", De Boer said on BT Sport's Premier League Tonight on Saturday.

Mourinho, clearly angered by De Boer's comments, fired back at the ex-Netherlands star by branding him the Premier League's worst manager of all-time.

"Frank De Boer, seven matches seven defeats and zero goals".

"If Marcus would be coached by Frank, he would learn how to lose". "The best thing that can happen to a kid is experiences and Marcus is having these". "I have to be honest and give the credit to the people of the academy that were responsible for his formation, to Mr. [Louis] Van Gaal, who was responsible for his first season".

Do you think Rashford deserves more game time under Mourinho?

'But if you go to his numbers and how many matches he played with me last season and this, I would say probably he's in the top five players with more matches in the two seasons. He was Mourinho's most used player in 2017, with 61 appearances for United in all competitions. Of course not. He's a player we trust. I'm really happy too.

"I am really pleased with everything".

The La Liga club held Liverpool 2-2 at Anfield in the groups before coming from behind to draw 3-3 at home, and are more than capable of getting the away goal that could prove fatal to United's progress.
