Law has nothing but praise for the job Jose Mourinho did in his first season in charge at Old Trafford as he managed to win three trophies and help bring Champions League football back to the club.
Mourinho managed to silence his critics with a successful end to the campaign after they failed to challenge for the Premier League title and were unable to finish in the top four.
Former heroes including Rio Ferdinand, Paul Scholes and Michael Owen all criticised the number of goals that came from the United attack and stressed that Mourinho needs to address that problem during the summer.
The Manchester United fans would certainly settle for a modern day equivalent of Law who remains one of the greatest strikers in the club’s history after scoring 237 goals in 404 appearances.
With Zlatan Ibrahimovic unlikely to make a return to Old Trafford and Rooney expected to make an emotional departure from the club, United will be keen to bolster their strike-force in the coming weeks.
Law is keeping a close eye on developments at United during the summer as big names like Griezmann continue to be linked with a move, but the 77-year-old feels Mourinho will get the targets he needs to make them a major force once again.
Law said: “When you get a recognised striker you hope he will score goals and he (Griezmann) is a very good player. I am sure they will strengthen that area and will know what is required.
“Jose will know what he needs and I am sure he will get that.
“I remember Bill Shankly when I was a youngster and his philosophy was to get a good defence and don’t concede goals. But at the other end you need to have players who can score goals.
“You get the defence right to begin with and then you get the forwards to score goals. There is a lot of competition for the best goalscorers and you have to pay a lot of money which they are doing.
“It would be a bonus if we could get one of the young strikers to come through.”
Law has nothing but praise for the impact that Rooney has had during his 13-year stay at Old Trafford and feels it will take a big man to replace him in the future.
One player who is already been talked about as a long-term replacement is Marcus Rashford following his sensational burst into the first-team and Law sees no reason why he cannot maintain his quality in the first-team.
Law added: “He (Rooney) has been a great player for the club and it would be a sad day if he decides to go. He has been a wonderful player for Manchester United and it is down to him what he wants to do.
“I wish Marcus the best for the future. Without a shadow of a doubt he has looked like he has been there for years.
“There is no arguing with the fact he has been taken out of the Under-21 team and is now a regular in the senior England team.”
Law was back at Old Trafford on Thursday as he met up with Sky Sports presenter Jeff Stelling who is currently taking part in March for Men in aid of Prostate Cancer UK .
Stelling is walking 400 miles from Exeter City’s St James Park to Newcastle United’s St James’ Park and will visit over 40 football clubs along the way.
Law said: “It is fantastic what they are doing. They are doing a 15 day walk and I can hardly walk down the street without getting tired!
“It is incredible what they are doing. Both Manchester and London have had problems recently, but the response has been fantastic and we will keep fighting on. When you have something like this everyone comes together.”
