#1 Ole Gunnar Solskjær (Manchester United1998-99)
Norwegian forward Ole Gunnar Solskjær is, without a doubt, the greatest squad played that has played for any club anywhere in Europe and during Manchester United's historic treble-winning season in 1998-99, he was directly responsible for helping the club in completing that achievement.
With Dwight Yorke and Andy Cole scoring for fun and Teddy Sheringham as the backup, Solskjær had to play much of the time as a substitute. He made only 17 starts across all competitions but also made 20 appearances as a substitute.
However, he was almost always proved to be an influential substitute as he went on to score 18 goals in the season and the most famous of them came in the Champions League Final at the Camp Nou against Bayern Munich.
After having equalized in added time, United clinched the game with a Solskjær goal in the dying moments of the game to win the trophy and complete the treble. There has never been a better squad player.
