Manchester United defender Luke Shaw has expressed his frustration of not making it to the squad in the Red Devils' 4-0 defeat to Chelsea and has vowed to prove his worth to Jose Mourinho in order to cement his place in the starting lineup.

The Portuguese tactician's Stamford Bridge return ended in a disappointment as the Blues registered a crushing victory over the 20-time English champions. Mourinho helped United bounce back by defeating Manchester City in the fourth round of the EFL Cup draw, where the full-back started on the left side of the back four.

Mourinho publicly criticised Shaw for his errors in his side's 3-1 defeat to Watford and since then he has not been a regular in the starting lineup. However, an injury to Eric Bailly against Chelsea saw Daley Blind move to the centre-back position, which allowed the left-back to return to the starting lineup for EFL Cup clash against City.

Shaw is determined to continue in the left-back position as he looks to fight for a place in the starting XI.

"It's normal you're frustrated on Sunday because I would have loved to play in that game [against Chelsea] but it obviously wasn't meant to be and at the end of the day it is the manager's decision," quoted Shaw as saying.

"Obviously with the injury with Eric now it might be my time to step up and show the manager what I can do and that he can trust me.

"The first half [against City] wasn't the best of mine. I thought I did good but on some of the crosses I wasn't maybe getting tight enough, but he [Jesus Navas] is a very quick player and it was quite tough."

"But I came out in the second half and I felt much better. I was closing him sharply, we made sure he got no crosses in and I felt really good. Hopefully I play on Saturday and get another 90 minutes and a good result with that."
