But James had the last laugh this time around.
Following a rousing 121-99 win over the Boston Celtics on Sunday, LeBron James said his four new Cleveland Cavaliers teammates fit in as if they have been with the team longer than the three days that have passed since they were acquired at the trade deadline.
The five-time NBA All-Star (including his 2018 call up) is now in the top 10 in the league for points per game, averaging 24.9 (as of February 6). He chipped in eight during a 13-2 burst that turned a one-point deficit into a double-digit lead.
The Cavaliers broke free from a tight start with a strong performance in the middle quarters, outscoring the Celtics 33-20 in the second and 31-22 in the third.
Varane: Zidane key to my time with Real Madrid
Asensio has started just 10 times in La Liga for Madrid this season, scoring four times and registering a further four assists. The Catalan paper reports Joachim Loew is now leading the race to replace Zidane at Real Madrid at the end of the season.
The flurry of trades have added some more youth and versatility to the Cavs roster and should help them improve on defense but it will be interesting to see how well the team is able to gel by the time they come up against the Celtics on Sunday.
James gave Cavs fans a scare when he left the game after suffering an apparent right leg injury late in the first quarter.
Irving led the Celtics with 18 points and five assists.
James are leading in four major statistical categories for the Cavaliers: points (26.4), assists (8.9), steals (1.6) and blocks (1.0) per game. The 10-time NBA All-Star played 15 seasons in Boston, winning the one Finals series and playing in another in 2010. Allen's Instagram post with the hole-in-one making George Lopez (damn him) and the Celtics reunion photo from the game just further prove that fact.
