CHELSEA star Callum Hudson-Odoi was hooked at half-time against Manchester United - with Thomas Tuchel confirming it was 'partly tactical'.
The 20-year-old started at right wing-back for the crunch top-four clash.
But he failed to re-emerge for the second half with the rest of his Blues team-mates.
As Reece James replaced him, pundits including Gary Neville speculated that he'd been hooked again, as he was recently at Southampton after just 31 minutes, with Tuchel blaming a poor attitude.
Hudson-Odoi returned to the bench, apparently in discomfort, with strapping and ice on his knee, but Tuchel confirmed he was only a 'little injured'.
The Chelsea boss said: "[He was] a little bit injured.
"The reason [he was replaced] was a tactical reason and a little injury, a combination, because we switched to a back five in defence and covered the wide position from [Marcus] Rashford in between [Cesar] Azpi and Reece James.
"In the second half, that was not an option to use Callum there and that’s why it was a tactical choice."
England international Hudson-Odoi was involved in the goalless draw's most controversial incident.
Manchester United were convinced they should have had a penalty in the 15th minute, after the ball appeared to strike Chelsea's No20's hand in the box.

Play initially continued, before referee Stuart Attwell was instructed to go over to the monitor to give it another look.
On co-commentary duty, Neville was convinced that a spot-kick would be given.
Hudson-Odoi and Azpiliecueta could both be seen berating Attwell as he consulted the replays.
Neville and United were left gobsmacked, however, when Attwell opted not to give a penalty after all.
After the game, a furious Solskjaer told Sky Sports: "100 per cent we should've had a penalty, it's a hand that slaps the ball in a not very natural position.
"100 per cent nailed on but nothing I can do about it now.
"He [the referee] had the chance to give it but I can't understand it, it would've given us a 1-0 win or it opens up the game and it's a better game for everyone."
