Jamie Carragher has warned Bruno Fernandes to expect a “completely different” experience when he plays his second Premier League game on Monday night.
He has spent more time with his new team-mates in their warm weather training camp in Marbella and will now look to make his mark on the English top flight.
But Liverpool legend Carragher believes he will face a much tougher test at Stamford Bridge in a game where he reckons the midfield battle will be key.
Carragher told Sky Sports: “I always think midfield with Chelsea because Chelsea have got a really strong midfield in Jorginho, Kante and Kovacic in there.
“It’s really strong and they’ve still got people like [Mason] Mount or [Ross] Barkley who could drop in there also.
“With the new signing for Manchester United, Bruno Fernandes, coming in there as well, he made a decent start against Wolves in his first game.
“He’s been away with United now, getting to know his team-mates and integrate more so it’ll be interesting whether he plays central midfield or off the front as he played both positions in the game against Wolves.
“It will be interesting what happens in that area because that’s something where United wanted to strengthen, with [Paul] Pogba and [Scott] McTominay being out, so I think that’s where the game will be won.
“It will be interesting to see how Fernandes copes. It’s completely different playing away at Chelsea than playing at home to Wolves.”
United trail fourth placed Chelsea by six points in the Premier League table – and Carragher believes their top four hopes will be over if they lost in west London.
He added: “It’s a big one. Teams now fighting for the top four and Liverpool are possibly too far ahead I would think so the big battle for the rest of the top sides is whether they can secure Champions League football for next season.
“I think this one is a real big one. I don’t think it’s just about this season. Both managers, young managers, know it will have a big bearing on how they can do their job going forwards because Champions League football means more money, you can attract better players.
“It just means they’re in a position then to have better seasons next season and also do a better job over the long term of the clubs that they’re at.
“Where Chelsea are at now and with the lead they have and being at home, if they could reverse the result they had at Old Trafford and get a win against Manchester United I think they’d be in too strong a position to be caught, certainly by Manchester United.”
